Re: 70 GMC 4wd version
 

Been working in it here and there. Gonna try and get cab off before winter hits to hard and i cant get buddies over in the cold.

The list before cab goes on.
exhaust, tailpipes and passenger side.
detent cable for 700r4
trans cooler lines
distributor gasket, cant forget it after it will be easier now then later.

Today i got the new diff cover on the 12 bolt, driver exhaust built back to muffler, and my lower shock mount welded on the rearend.

I also finally got argon co2 tank for my welder, before now it was just flux and k hated it, i always took things to work and welded them with our 220, well the exhaust and shock mounts woulda been hard to do that with. Much happier now.

Side shot of exhaust. I strongly dislike being able to see exhaust hang under the frame.

Re: 70 GMC 4wd version
 

Nice well thought out clean build, I agree on the exhaust.

Re: 70 GMC 4wd version
 

The truck is coming along nicely! I like the exhaust routing. I may have to rethink...or maybe think....about mine.:lol:

Re: 70 GMC 4wd version
 

Got some done on the exhaust, got it far enough tonight so i can order the rest of my bends.

Re: 70 GMC 4wd version
 

First time i have seen this while leaving the door on, but if it works and the body lines match up well its all good. :)

Re: 70 GMC 4wd version
 

X2 Not easy repairs to make and looks like your really in it...

Re: 70 GMC 4wd version
 

I just threw the door back on while i test fitted the cab corner, it off again now

Re: 70 GMC 4wd version
 

I really thought when i started this i was gonna completely redo the frame then just swap everything over, seeing as it was a running driving truck with all systems in working order.

Instead i had the might as well disease.

Heres a list of those things


Rear disc, which leads to new master and proportioning valve.
electric fan, needs wirinn harness, along with alternator upgrade
headlight relay mod, new lenses with h11 bulbs
new plug wires with seperators.
new body ground kit
new battery cables
optima battery
Was gonna just swap cab, well decided to fix all rust
doors and fendefs have some rot so gonna replace them.
which leads me to having to paint the whole thing, i am researching alternatives to actual spray jobs after my current house wont run my air compressor.

And this is longer im sure.

No real pointto this post other then forme to keep track of what im doing and have done.


Today i spent half of it running wires, headlight relays, move steering coloum 2 inches closer to firewall, sanded back of cab, measure for battery cables. So progress just no pics.

I am very excited to see the cabon the frame tho.


Thanks for looking

Re: 70 GMC 4wd version
 

O i do have one question, does anyone see issues with this valve cover clearence?

I already moved the engine forward 2 inches from factory.

I was thinking of a 1 inch body lift but not sure how i would go about raising front bumper after it rolls under the frame so it wouldnt just move straight up.

Any ideas, thoughts or concerns are appreciated

Re: 70 GMC 4wd version
 

Well no ideas on body lift unless you can build a bracket to lift the bumper up slightly but would have to notch the bottom of the front of the frame because of it's design, nice progress on the truck, doing it better than just good takes extra time, but worth it. Only concern i see is the wiring so close to the exh manifold on the passenger side, may get hot eventually. Valve covers are close but the engine does move the other way so may not be a concern to the firewall.

Re: 70 GMC 4wd version
 

Use shallower stock type valve covers, move the engine further forward, or lift the cab. I guess you could modify the crossmember and mount brackets to lower the engine. Since you lifted the truck you shouldn't have issues with front axle clearing the oil pan.

Re: 70 GMC 4wd version
 

Engine has roller rockers so cant go smaler valve covers. As off now i have about 1.5 inches between water pump and electric fan so thats an option.

I think there is adequate clearence but i dont know, i think body liftis easiest but hate the front bumper situation.

Its hard to believe this motor fit fine in 2wd configuration, yet it seems so close in 4wd fashion.

Thank you and mud man for your input, i appreciate it.

Re: 70 GMC 4wd version
 

That's because the 2wd bbc mount brackets place the motor about 2-1/2 to 3" further forward. 4wd never came with a big block and all small blocks were further back for better weight distribution.

Re: 70 GMC 4wd version
 

I don't really see the problem, so it is close but not hitting. It works.

Re: 70 GMC 4wd version
 

I underatand what your saying, but this same setup, same motor, valve covers, same electric fan, and on the 2wd frame i had more firwall clearence and more room between the water pump and radiator.

I agree with mud man, i think im gonna rock it, engine shouldnt flex that much

Re: 70 GMC 4wd version
 

If your motor mounts are new and good quality it won't flex much at all and always goes towards the passengers side. All good. Sure you have more things to take care of.

Re: 70 GMC 4wd version
 

Are you running a short water pump?

Re: 70 GMC 4wd version
 

Yes it is a short pump.

Like i said in 2wd form i had about another 3/4 of inch at the firewall of clearence and it seemed like i had more at the front of the motor. But im not about to swap everything back over to verify.

I moved on i think all is good.

Re: 70 GMC 4wd version
 

Alot of progress, finished all wiring, all lights works everything has good grounds.

Also installed my front diff cover from chassis unlimites to match the rear, these things are pure beef.

Got the bed and front clip swapped over, front tire is a 35 rear a 33, im pretty sure im going 35s

Also started working on my fuel filler.

http://i114.photobucket.com/albums/n...ps3mw42mfo.jpg

Re: 70 GMC 4wd version
 

Fuel filler looks good, the 33's look small and the 35's just right.

Re: 70 GMC 4wd version
 

Your build looks great, If you haven't found a drive shaft any 1/2 ton with slip yoke should work 208 or 241 tc, if you can find one longer should be around 35.00 to have shortened. On your bumpers with the body lift back just weld a piece of angle on top of your frame and relocate holes for bumper, this way you don't loose any strength if you still want to tow a trailer, the front just cut your frame horns off and move them up an inch or whatever your body lift is. I have an 85 blazer I did it with a 3 inch body lift, bumper looks stock now.
Good luck and great work can't wait to see it finished.

Re: 70 GMC 4wd version
 

Nice transformation. Are you going white now on body color? Those big blocks are tight in there. I put one in a 69 k20 I pulled with and it was a sob to get the tall valve covers off it.

Re: 70 GMC 4wd version
 

Thanks diesel, yes its going to be white. Figured easiest to paint behind the cab now so i dont have tl pull the bed again.

Didnt realize its been this long on the build, my wife and i bought our first home march 18th and its been a month of no sleep, new carpet, close a few doors just to open another one, paint all rooms, new bathroom flooring, etc. But we moved in this weekend so in a few weeks i should be back at it.

Re: 70 GMC 4wd version
 

In my opinion you may have turning problems with the 35's. I think they will hit the back of the front fenders. You want to try your turning radius before buying tires.

Re: 70 GMC 4wd version
 

I agree on the tires hitting, my last 71 had 35's but needed min of 5"s of lift and were still close, but the 35's sure look better than the 33's.

Re: 70 GMC 4wd version
 

Could always look for the stock Hummer size tires, they were a 34.5" tire in the size of 315/70/17.

Re: 70 GMC 4wd version
 

Turning radius combined with hitting some bumps, rocks curbs or what have you..

I'd like 35's also but am concerned about hitting the fenders as well, my BDS 4" springs give me 12" from the top of the front tire to the top of the fender well with BFG 33's, just not sure its gonna clear the rear of the opening and would hate to spend the coin and find out i have a problem

Re: 70 GMC 4wd version
 

Appreciate all the concerns, i already bought the 35s before i even put one on. 500 for like new 35 bfgs wouldnt be hard to sell.

But they clear 100 percent fine, i drove the truck the 22 miles to my new house with no rubbing at all.

35s and 4 inches clear fine fore street driving, now that is with factory rallies so i dont have to worry about offset of aftermarket wheels.

I would never go bigger then a 16 on a old 4x4 so 315 70 17 where out of the question.

Re: 70 GMC 4wd version
 

Not sure what lift you have?

I'd like to know the lift size and if you get a chance can you post a pic of the wheel turned and showing a shot of the clearance to the rear of the fender opening?

This is for my information to help me decide if i should buy 35's next for my other set of rims.

Re: 70 GMC 4wd version
 

looking good. Great progress!

Re: 70 GMC 4wd version
 

Not truck related, but got a new trailer.

Re: 70 GMC 4wd version
 

That's a very nice trailer!

Re: 70 GMC 4wd version
 

nice build, any new progress?

Re: 70 GMC 4wd version
 

Truck is basically done, got interior in, everything underneath checked and tightened, painted (which i did a paint job most will hate on here), drove it around town about 300 miles so far.

Really need front inner wheel wells before i throw a rock into the hood, and need radio antenna cable, bed line bed, and turn signal lense.

Thanks for the interest

Re: 70 GMC 4wd version
 

Curious to know what the paint job is...

Re: 70 GMC 4wd version
 

Like i said alot wont like it.

Heres the most recent pics it wasnt done in these

Re: 70 GMC 4wd version
 

I got to thinking about thisnpost the other nighg, never did grt pics, but i have a 4 inch rough country lift, which everyone says wont clear, but i alsp have off road design shackles which are slightly longer then stock so i think thatmight be the difference.
