I lifted the hood on the Blazer . . . - Page 2 - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Jason915 · 04-17-2006, 10:31 AM

That is what I have on my truck 882's with 2.02" X 1.60" valves and it runs good and mine is just a 355. 882's actually flow pretty good for a factory cast head your 400 should run real good. Have you picked a cam yet?

Good luck

**Yukon Jack** · 04-24-2006, 11:43 AM

The engine guy called this weekend and said the motor is back from the machine shop. It cleaned up with the .020 bore job. The 882 heads also inspected out fine. I told the engine guy what I was looking for power wise - low end torque and he is going to pick the cam. He did a buddy's motor recently and did a great job so I have faith in him. I'll post up the specifics when I get them.

He has to order parts and then he will be putting it back together. It is moving along at a good pace, faster than I expected and can't beat the fact that he calls me to give me updates. Gotta love that.

Nice One YJ

So by this time next year you should be on the road with your Blazer too

hehehee

**Yukon Jack** · 04-25-2006, 02:05 PM

I sure hope it doesn't take me that long, but given the length of time it took to get the K20 on the road, well, anything is possible.

**Yukon Jack** · 05-09-2006, 09:42 AM

Not for more than 2 years has this baby sat on a front axle! Got the engine mounted to the tranny last night and wrestled the front axle in to position. What do you know, the front driveshaft looks like it is gonna fit. Need to pull the front axle out so I can open up the center pin holes on the spring perches a tad, then put it back into place and get ready to set the rear 14 bolt axle into place to get the rear perches positioned right then welded.

Getting closer!

**Yukon Jack** · 05-11-2006, 09:55 AM

I set the 14 bolt axle in place last night. The front Dana 44 is sitting on 4" lift springs. The rear springs are stock and right now there is a 4" block in place that was used with the Blazer's original axle. I made the spring perches about 1" taller than the stock ones but as it sits now the rear is too high compared to the front. The below pic doesn't show the stance very well - I will have to move the 69 so I can get a full side shot.

From the ground to the bottom of the rear wheel well lip is 43 3/4".

From the ground to the bottom of the front wheel well lip is 41 1/2".

Sure looks like a 2" lift block instead of the 4" lift block would get it sitting right.

Also, when the hard top comes off, do I remember that the rear will raise roughly 1" due to the loss of weight?

If anyone has a second and wants to post similar measurements to help get my stance leveled out, that would be cool.

Jason915 · 05-11-2006, 11:18 AM

Looks like it's coming along well, 2" blocks would be better anyhow I have spit lift blocks out of my truck before off roading.

**Yukon Jack** · 05-12-2006, 11:25 AM

Okay, got the K5 I think pretty level last night by insert a 2" spacer (just temporary) in place of the 4" block. Here's how it is sitting now. It looks a little low in the rear in the picture but when I'm standing there looking at it - it looks fine.

I think with the top off it will still have a good stance. The spring perches I made are long enough that I can move the spring pack center pin hole back about an 1" to 1 1/2" to get the rear axle located better in the wheel opening.

Now I have to look into a what to do for a 2" lift block. Not so sure the 4" blocks that I have could be cut down very easily - but that is something to consider. For now I don't think I will go with new rear springs.

Had a heck of a time centering the rear 14 bolt axle. I was measuring from the back surface of the drum brakes to the edge of the spring pack and while everything looked centered, the measurement was off by 1". Scratched my head for a while and finally saw that the driver side hub/brake unit is 1" wider than the passenger side. Changed to measuring from the edge of the rim to the spring pack and now the axle is pretty much centered. (still need to move it maybe 1/8" of an inch or so one direction.)

Not sure why the driver side hub/brake unit is wider, must just be the way the 14 bolt's are made.

Hopefully I will get out tonight and get the axle moved back a little then get ready to set the pinion angle. Then I need to take it to a friend to weld the perches in place.

Before I know it I'm gonna be ready for the engine to come back from being rebuilt

**Yukon Jack** · 05-19-2006, 05:42 PM

Guess whose motor is being delivered tomorrow at 1:00 p.m.

Too bad I don't have any free time this weekend to get it installed!

GMC71k20 · 05-20-2006, 12:33 AM

good job on all the progress. is this one going to get painted too?

DEFIANT NCC-74205 · 05-20-2006, 03:13 AM

Did that push bar come off of a '69 Charger? Just kidding!!

Jason915 · 05-20-2006, 03:38 PM

Stance looks good to me

**Yukon Jack** · 05-22-2006, 11:52 AM

Got the engine on Saturday now gotta find some of that elusive free time.

Here are some of the specs:

Degress .05" dur 204 Int. 214 Exh., Degrees ADV. dur 278 Int. 288 Exh., Inches Valve Lift Int. .420, Exh. .443, Degrees Lobe Center Int. 107, Exh. 117

Should be a good low end torque cam with the power range of 1000-4500.

The block was bored .020 over and the crank was cleaned up. It now has hypereutectic pistons and with the 882 heads with 76 cc the engine should have a compression ratio of about 9.5:1. These heads came off of a 400 so they have the correct steam holes.

The intake is an Eldebrock Performer and the carb is a Jet Stage II 750 cfm quadrajet.

The fuel pump is a Holley and the engine guy said to watch it cause it is 7 psi and he wondered if that might be a little too much for the carb.

The next two weeks are going to be a bit busy for me but hopefully I can find some free time in the evenings to get more done to the Blazer.

BobbyK · 05-22-2006, 12:00 PM

Nice...while it's out why not plumb in a fuel regulater.
If the pump turns out to be a little much for the carb you can always turn the pressure down.

Jason915 · 05-22-2006, 03:02 PM

Nice that should be a torque monster.

**Yukon Jack** · 11-08-2006, 12:47 PM

About time for a little updated I would say. Free time has been next to impossible to find for the last few months but got out to the shop the last two nights and got the pinion angle dialed in on the 14 bolt I'm swapping in. Monday night I got it close and got the measurement for the rear driveshaft. Took it in Tuesday for new u-joints, including change to a conversion u-joint for the 14 bolt I'm putting in, lengthening, and balancing of the finished driveshaft.

Went out last night and dropped the rear pinion down a touch, took more measurements and got the angles finalized. Now I need to mark where the shock tabs need to be and then pull the 14 bolt back out and run it over to a buddy's to have the tabs and spring perches welded on. When I get the axle back I will then install the Detroit locker and then I can reinstall and get the brake lines modified and connected.

A little progress, but I will take all I can get!

Oh, after I got that done last night I cracked open three cardboard boxes containing a new three piece rolling tool chest - I've been wanting one of those forever and Sears had a sale on their QuietGlide series chests that I just couldn't pass up. Got the intermediate draw chest for free. It should fit my needs very well.

**Yukon Jack** · 11-09-2006, 12:06 PM

Got out again last night, that makes 3 nights in a row - that doesn't happen very often these days!

Got the rear axle pulled back out and now it is ready to go to my buddy's for spring perch welding - maybe get that done this weekend. Had to take the driveshaft back to get a different u-joint for up front. It needed a conversion u-joint like used on the rear that makes me guess that the NP205 that I'm using must have come from a 1 ton for it to need a 1350 u-joint. At least I didn't think that they usually used that large of a u-joint. Not sure.

Also had some clearance issues with the grease zert on the axle side of the driveshaft. The changed the position so now I will need to see if it will work correctly and still be able to get the grease gun on it.

Sure is nice to be making some progress!

Here's the driveshaft

And here is the 14 bolt with the spring perches dialed in

And, of course I have to show off my new tool chest

70rs/ss · 11-09-2006, 02:23 PM

Nice work, how are you relocating the perch locator? I have seen several of these and the tires seem to be too far back for the front and too far forward on the rear, have heard some say zero rate will fix it, my question is how? I have a 72 with 1/2 ton under it and I am sitting on the fence about 2wd'ing it or the 3/4 ton drivetrain I have, one ofr the other. Any help or advice would be great, cause if I lift and 3/4 ton it I want it to look correct.

**Yukon Jack** · 11-09-2006, 02:30 PM

I put offset holes in my spring perches and also drilled new relocated holes in the 2" lift blocks - combined this got the rear axle located very well in the wheel well. The tires definitely looked totally wrong before making that change.

The zero rate gives you 1" of lift and has holes I believe in three different locations to allow you to position the axle a little forward or back.

**Yukon Jack** · 11-09-2006, 02:36 PM

Here is how the Blazer looked before relocating the holes - this is with the 14 bolt in place with the 2" lift block and the spring perches that I made that are a bit taller than stock.

It doesn't look like I have a picture showing how it looks now - will have to snap one when I get the axle back under the K5.

**Yukon Jack** · 11-10-2006, 10:26 AM

Got out for the 4th night in a row - on a roll for sure. Found all these spiders in my shop last night

[IMG]http://yukon.b0xen.us0njack.com
Having a little trouble identifying their species but the good thing is they are now out making way for the Detroit locker for the 14 bolt going into my 70 K5.

Everything I read said the swap was pretty easy and that is definitely true - the hardest part so far has been getting the ring gear bolts torqued to 120 ft/lbs - having a hard time using my vise to secure the carrier to allow me to torque the bolts enough.

I asked this question in the 4x4 section but will throw it out here also:

Does anyone know if I need to use any sealant on the 8 bolts that the hold the axle shafts to the hub? When I pulled those bolts they seemed to have something on them and there was a little blue RTV visible on the back side of the axle flange when I pulled the axles away from the hubs.

The materials I read about installing the locker didn't mention using any sealant in that area.

gringoloco · 11-10-2006, 12:32 PM

Assemble the axle, put it in the truck and set the parking brake. Then you can torque those ring gear bolts.

**Yukon Jack** · 12-05-2006, 10:46 AM

This weekend got some free time during the day on Saturday (might I add, that never happens!) and my wife said, why don't you go work on the Blazer

so off I went.

About a week ago I got the Detroit Locker installation finished, got the rear cover installed and fluid back in the differential.

A few days ago I got the new rear brake lines bent up so on Saturday I got the new rear rubber brake line installed and then jacked the rear of the Blazer way in the air and rolled the 14 bolt in place. Got the u-bolts in place and now the Blazer is finally attached to the new 14 bolt. Stance is pretty good and the rear axle is located fairly centered in the wheel wells now.

Now on to reworking the front brake lines a bit, pulling the spare sbc that is sitting in the engine bay and I can finally reinstall the rebuilt 400 sbc! Geez, at this rate, I will be done by . . . well, I'll be done when I get done. I've learned not to set any expected completion dates.

I have seen several of these and the tires seem to be too far back for the front and too far forward on the rear, have heard some say zero rate will fix it, my question is how? I have a 72 with 1/2 ton under it and I am sitting on the fence about 2wd'ing it or the 3/4 ton drivetrain I have, one ofr the other. Any help or advice would be great, cause if I lift and 3/4 ton it I want it to look correct.

I put offset holes in my spring perches and also drilled new relocated holes in the 2" lift blocks - combined this got the rear axle located very well in the wheel well. The tires definitely looked totally wrong before making that change. The zero rate gives you 1" of lift and has holes I believe in three different locations to allow you to position the axle a little forward or back. __________________ 1970 Blazer with a 400 sbc and 4" lift 1980 Pontiac Trans Am, 455 Oldsmobile 2012 Kawasaki Concours 14

Here is how the Blazer looked before relocating the holes - this is with the 14 bolt in place with the 2" lift block and the spring perches that I made that are a bit taller than stock. It doesn't look like I have a picture showing how it looks now - will have to snap one when I get the axle back under the K5. __________________ 1970 Blazer with a 400 sbc and 4" lift 1980 Pontiac Trans Am, 455 Oldsmobile 2012 Kawasaki Concours 14 Last edited by Yukon Jack; 08-22-2009 at 04:23 PM.

Found all these spiders in my shop last night [IMG]http://yukon.b0xen.us0njack.com Having a little trouble identifying their species but the good thing is they are now out making way for the Detroit locker for the 14 bolt going into my 70 K5. Everything I read said the swap was pretty easy and that is definitely true - the hardest part so far has been getting the ring gear bolts torqued to 120 ft/lbs - having a hard time using my vise to secure the carrier to allow me to torque the bolts enough. I asked this question in the 4x4 section but will throw it out here also: Does anyone know if I need to use any sealant on the 8 bolts that the hold the axle shafts to the hub? When I pulled those bolts they seemed to have something on them and there was a little blue RTV visible on the back side of the axle flange when I pulled the axles away from the hubs. The materials I read about installing the locker didn't mention using any sealant in that area. __________________ 1970 Blazer with a 400 sbc and 4" lift 1980 Pontiac Trans Am, 455 Oldsmobile 2012 Kawasaki Concours 14 Last edited by Yukon Jack; 08-22-2009 at 04:23 PM.

Then you can torque those ring gear bolts. __________________ -Chris Instagram _elgringoloco_ '70 Short-Wide How to: Ruin a perfectly good C10 ‘70 Blazer ConversionHow To: Ruin a Perfectly Good 4wd '72 Highlander How To: Ruin a Perfectly Good K/5 (SOLD) '72 Blazer 2WD How to: Ruin a perfectly good Blazer (SOLD) '05 Yukon Daily Driven (not so stock) Yukon (SOLD) ‘07 Yukon Denali (daily) Members met list: SCOTI, darkhorse970, 67cheby, 67cheby'sGirl, klmore, porterbuilt, n2billet, Fastrucken, classicchev, Col Clank, GSFMECH, HuggerCST, Spray-Bomb, BACKYARD88, 5150, fine69, fatbass, smbrouss70, 65StreetCruiser, GAc10boy

This weekend got some free time during the day on Saturday (might I add, that never happens!) and my wife said, why don't you go work on the Blazer so off I went. About a week ago I got the Detroit Locker installation finished, got the rear cover installed and fluid back in the differential. A few days ago I got the new rear brake lines bent up so on Saturday I got the new rear rubber brake line installed and then jacked the rear of the Blazer way in the air and rolled the 14 bolt in place. Got the u-bolts in place and now the Blazer is finally attached to the new 14 bolt. Stance is pretty good and the rear axle is located fairly centered in the wheel wells now. Now on to reworking the front brake lines a bit, pulling the spare sbc that is sitting in the engine bay and I can finally reinstall the rebuilt 400 sbc! Geez, at this rate, I will be done by . . . well, I'll be done when I get done. I've learned not to set any expected completion dates. __________________ 1970 Blazer with a 400 sbc and 4" lift 1980 Pontiac Trans Am, 455 Oldsmobile 2012 Kawasaki Concours 14 Last edited by Yukon Jack; 08-22-2009 at 04:24 PM.
