I figured if I went manual I could mount the cab and get the truck running. Then worry about converting back to power later.

I believe if you check around there are master cylinders made to work with disc brakes that are pedal mount and made to be mounted under the floor. I would do about anything to keep my disc brakes.:gmc2:

On average following skymangs directions how far back does a sbc get pushed back roughly? I'm just trying to figure out if i can get away with s10 v8 swap motor mounts from jags that run. One less thing to fab so i don't mind spending 50 bucks for mounts if they will work.

Mounts I'm talking about

Re: S10 Swap how to
 
rtinniste it does not take much to fab motor mounting pads. I had the cab placed on the chassis than bolted some 1/4" or thicker flat plate to the to the original motor mount bolts in the frame. I used 2 1/2" x 1/4" wall square tubing with holes drilled to match motor mounts. I moved the engine around and trimmed the square tubing for height until I liked it. Make sure you know what your steering shaft and exhaust need for room. Sounds kind of involved but all it requires is basic fab skills. I ended with the motor set about 3/4" to the passenger side and about 1/2" clearance between valve cover and firewall. Than fab trans tunnel as needed. Be sure to keep the crank center line parallel to the frame rails:gmc2:.

I got these from amazon for $96 trans dapt 9906. The thing I ran into when using these were easier then fabbing bracket front scratch. If you running a smallblock chevy you really need to have a short water pump, so you have enough room for a fan. You may have a problem with the fuel pump bump sticking out of the block interfering with the bracket. So you will have to put the bracket on the frame and the motor mounts on the block. The problem is that the factory motor mounts on the frame have a nut on the other side that you cant get with a wrench unless you cut a access Hole in the frame like I did on both sides. Nice part is it's not a structure bracket. Just be careful not to cut off to much or drop the nuts in the frame. Then on the drivers side mount. Two hole will have to be ovaled out on the frame to be able to fit the bolts through the bracket. Then you will only be able to go so far back because the passanger head on small block Chevys are offset and will touch the firewall and the driver side headwill be about an inch away. So you may need to do a small notch in the firewall to fit. Un fortuntally dropping a v8 into an S10 with conversion bracket gives enough clearance for everything. But dropping a V8 onto an S10 frame in a advanced design truck requires some work. And isn't just a bolt in. But you may have a few differences because the frames can very a small amount from year to year.

I used a champion ec180 70s and 80s Toyota Land Cruiser radiator off ebay for $120. It's a 2 row 1 inch core so it cools more efficient then a 4 row. Work perfect for a small block chevy. But it has 1 1/2 inlet and outlet.

Here is what it look like in the truck. I had to Cut the cross brackets, bottom of the radiator surround and welded in a piece of angle iron. Just have to weld in a bracket the connects the frame to the bottom of the surround. The radiator has enough clearance room with the hood on.

Dude first off thank you this was the info I was looking for.
And i agree if i can buy the mounts I'd rather do that saves time from having to fab them. Short water pump was going to go on regardless i have a spare brand new short water pump from my dads c10 build. i was planning on notching fuel pump clearance on the frame seems like everyone has to do that. And yea those motor mount bolts are a pain ask me how i know i ended up just drilling the heads off on both mounts luckily the ends all fell out of the frame.
Main thing was i wanted to make sure the motor mounts will push the motor back far enough to the firewall to clear a fan with a short water pump. So ill order up the jags that run mounts gives me 3/4" side to side adjustment which should help with snaking the steering linkage in there.

Now another question i know s10 headers will work i also read somewhere that Camaro exhaust manifolds fit? How about block huggers i can get a pair of headman blockhuggers for a decent price.

Great information. I plan to use the 4.3 V6 that comes with the S10, do I have to make a lot of mods besides moving it back 7"?

I think with block hugger the outer header pipes and exhaust flange might be to fat. You can always get a painted set from jegs mock it up and if it doesn't work out, they have a good return policy. How about ram horn exhaust manifolds. I have not tried them but you can get them used dirt cheep.

These were center mount cabs, you will need to weld a 6"x6" 1/4" plate on the bottom of the floor on each side to re-enforce the floor for the new cab stands.

If you have a 51-54 cab, you will need to remove 1/2" from the "above frame" portion of the rear cab stands and add a 1/2" delron spacer above the stock S10 body mount (this fits between the factory floor braces)

I bend the lower legs out at a 15deg. angle to decrease stress on the side of the frame

both these use the stock S10 body mount bushings above the cab stands.

In the above post, Chris has stated to remove 1/2" from the stand if you have a 51-54 cab and use a 1/2" delron spacer. In May, before the accident, I was talking with Chris via e-mail and he stated he was not using the delron any longer and was using an early camaro radiator mounting and gave me the link that shows the item.

Has anyone used these and/or what do you know about these? Thanks, Clay

Re: S10 Swap how to
 
Those you have linked are for the radiator Not the cab if I understand you correctly. The rear cab mounts need a spacer to clear the U brace that runs underneath the back. I thought I remember Chris posting that he was using the S10 core support bushings because they would fit into the U brace without modification. They were narrower.
Jeff

Clay54 11-22-2015 10:59 PM

Re: S10 Swap how to
 
Thanks Jeff, for your quick response. I can send you the e-mail from Chris that he sent me when I ask about this very thing. I thought he was talking about some small round support but this is the link he sent me. Yes, in my opinion, the S10 support is still used and these are in addition. First the cab stand then the S10 support and then these or the delron spacer to go in that space you are calling the "U brace".

I was hoping someone that had done this could comment about using these mounts. Thanks again, Clay

I have a new tip I just figured out. Instead of using the DeLeon spacer and cutting the rear mounts 1\2" shorter on the 51-54 cabs, you can make them normal height, and use the s10 core support bushings instead. They are smaller diameter than the cab bushings, and will tuck right into the 51-54 rear cab brace.

Thanks again Jeff. That's the one I have been looking for. When I first read this, I began to look for S10 core support bushings and could not really find anything and I questioned Chris by e-mail and that is when he responded with the link I posted above saying "this is what I use".

I have been searching through all the builds that Chris has posted trying to find the above comment. Thought I had lost my mind but I knew Chris made the comment somewhere on this website. I have read this S10 swap sticky time and again and I guess I just past it up. Appreciate the help. Got your PM and will get that e-mail to you soon. Thanks, Clay

Coldshot 12-11-2015 01:04 PM

Re: S10 Swap how to
 
Clay, I responded to Chris when he brought it up. I'm using an energy suspension bushing kit and the smaller bushings came in the kit for the front clip bushings. Kit was about $80
I unfortunately had already followed the 1/2" drop suggested and when I put it together I thought I did something wrong cuz I went straight to the smaller bushings for the cab and the "C" brace dropped right over them. I added 1/2" worth of washers on top for now. Will need a permanent fix later.

Just order new bushings, the non poly's are cheap (I got poly) you see the bushings and it will make complete sence.
I'll try to get a pic up on here if I can

Clay54 12-12-2015 12:14 AM

Re: S10 Swap how to
 
Coldspot, a picture would be great, I would really appreciate that. So far, this does not compute to me. Is there anything you are using that looks like the bushings shown in the link I provided above? Thanks for your help. Clay

Sim6 12-12-2015 01:21 AM

Re: S10 Swap how to
 
clay,
what part doesn't make sense? Why the cab mounts are different heights from front to rear? why there are 3+ inches off the frame? Or what to use that will fit in the rear brace?
Jeff

Coldshot 12-12-2015 02:08 AM

Re: S10 Swap how to
 
The reason for the 1/2" difference is because the normal cab bushings are pretty fat. The other bushings are thinner. The "C" brace thing under the cab where you mount to wont go over the regular cab bushing but the front bushings are thinner in girth so they fit into the "C" the "C" is 1/2" deep. I just used all front mounts under my cab from the poly bushing kit worked great.

I'll take some pics when ever I get home.

Long 14+ hr days never end I tells yea

Re: S10 Swap how to
 
http://i1310.photobucket.com/albums/...psgcstmpvv.png

In that pic the very front pair and the smaller bushings you can see there 4 larger ones landed up in the second row and the rest are the corasponding peace's that go underneeth.
If you get an extended cab kit you get 4 small ones like I did or you can just use the smalls for the back and normals for the front. I couldn't open the link you posted, but these are what I have and they are pretty cheap.
You can always just use delrin pucks or shaved down hockey pucks, anything will work lol

Clay54 12-12-2015 07:02 PM

Re: S10 Swap how to
 
Coldshot. thanks. Pictures are worth a thousand words. I assume these are S10 bushings of some sort. These bushings are what I thought Chris was referring to when he sent me that link that shows some long somethings that don't make any sense to me at all. Now I think I might be back on track, I have seen some kits that have what looks like the bushing you show on the second row setting on top of S10 cab mount bushings. And no, I will not cut the rear mounts 1/2 inch shorter. Thanks again.

Jeff (Sim6), I understand why the cab stands are different height-not sure about the 3" off the frame though. Different height is to level the cab on the frame, I think. Yes it has always been what goes in that C brace. Chris stated to use something instead of the delron and when he sent me that link which was very confusing as those long black pieces of rubber just didn't make any sense to me. I know we have discussed this previously and you suggested Chris might have misunderstood what I had ask him. Not sure and it doesn't matter now as I think I now know what he may have been referring to.

Thanks to you both. Clay

Here are the measurement I have actually measured and just some info I collected. Hope this helps others. It worked great for me. I don't have any info on the s blazer but that could be another option for a rear axle. For those who don't know what a gov lock is. It's a gm locker. Some call it a posi but it seems to work like a limited slip to me.To test if it works ,you have to be spinning the wheels at about 10 mph. When one wheel slips the other will engage.To get both wheel to spin in the same direction. But in most cases that's not possible.so another way is th spin one wheel really hard and fast. You should here a little clunk and both wheels should spin in the same direction. In non lock mode both wheels will spin in the opposite direction. This info is not gaurantee. Gm does odd things at times. You should always double check.

Good info I remember this pic when i was searching for my rear axle. Everyone i called had no clue if it was a 7.5 or 8.5 and people that knew they had a 8.5 want $500 plus.

Another note about rear ends I'm running a 7.5" 4wd axle from a blazer and my rear calipers hit my bedsides so I had to cut about 3 inches up to clear the brakes. That should only apply to bagged trucks that will lay running boards or low static rides I'm not c notched either btw.

And the stock s10 wheels also have about a 1/2" of clearence against the bed so watch your backspacing anything more then 3.75 won't work the stock 15x7 3.75 s10 wheels will rub when the suspension flexs unless you use spacers. Get the zr2 axle should be perfect.

I'd just hate to see someone waste money on a standard 4wd axle and have that issue doesn't bug me because i was planning on reverse offsets anyways so that equates to deeper lips!! I just cringed when i had to take my cutoff wheel to my original bed that's rot free oh well

Also olds bravada should all be gov locked and I think I saw somewhere that they are the 8.5 but my neighbor that runs the local pick a part said that's not true. I havent looked that deep into it just when i was cruising the web.
But the bravada axles seem more plentiful and better priced. Car-part.com also helps when your on your search!!

Re: S10 Swap how to
 
^^^^^
That's what I got my axle out of and it's 7.625 ring. The code on the Glove Box was GT4 G80, that is, 3.73, Posi.

I too have heard the 8.5 came in these but I don't believe it, never seen an 8.5 in a Blazer or Bravada, any year. I have heard you can find an 8.5 in a 4x4 manual trans, never seen one of these trucks at a yard though.

If I had known about it, I would have gotten a 8.8 out of an Explorer and after a certain year, 2000 I think, they all had Posi and Disk brakes. And best of all, they practically right drop into an S10.

The 8.5 came in all S10's and Sonoma's (1998 to 2003 not sure of the previous generation) that were equipped with a manual transmission, 2wd trucks had the narrowest version and 4wd ZR2 trucks had the widest version.

I have seen astro van parts and jeep cherokee parts but I am not totally clear on what exactly to mix and match. Any help will be appreciated.

Not trying to step on your toes, but the only s10 that had the 8.5 rear end was the four-wheel-drive zr2. All of the rest of them had the 7.5.

It's funny, just earlier today I heard a quote, "Believe nothing you hear and only half of what you see", which applies so well to this topic.

I've heard what the elusive S10 8.5 in. is in so many different ways, from enthusiasts, car junkies, self proclaimed S10 subject matter experts, and dealer mechanics or parts counter guys. Everyone has a different answer.

Before I believe anything, I'm going to have to see it with my own eyes or receive a personally signed and notarize options list from Mary Barra herself.

It will work just looks a little narrow. That's what I'm running for now. Also depends on your power plant. That rear end won't hold up to buku power. Not what the threshold is.

the 98-03 xtreme trucks and blazers with the 4.3 and 5 spd trans did indeed come with an 8.5 rear, thats in fact the easiest way to find an 8.5 for a 2wd. also, the 94-03 trucks and blazers with the 4.3 and 5 spd could have an 8.5, but it wasnt a sure thing for all of them, I forget the RPO code to look for but google will have it.
