Updating the 72 GMC
 

We did this truck about 12 years ago unfortunately I over charged the battery and it leaked. We are pulling the nose off to clean and re-paint the core support, battery box and the inner fender. While we are at it I decided we would re-seal the engine and one thing lead to another. More to follow.....

I have a 72 GMC Sierra Grande.
Whenever I see anything "big" that needs to be done,
I just think to myself . . . ."next owner's problem" !
Good luck !

Re: Updating the 72 GMC

Oooooooo fuel injection, that's high up on my list of things to look into.

Re: Updating the 72 GMC
 

You are going to love fuel injection, I know I do.

Re: Updating the 72 GMC
 

This is our second FAST EZ EFI install. The first one was on my 1966 Buick Skylark with a 400. We love it.

I'm currently installing a FiTech on my 69 Camaro.

Re: Updating the 72 GMC
 

Nice.

Re: Updating the 72 GMC
 

I thought about going with a hydro-boost just so the brake master cylinder wouldn't stick so far out from firewall like it does with the stock booster. Are those brackets behind the hydro-boost needed like that? If so, I am probably going to scrap the idea.

I'm thinking about using a Corvette master cylinder with a 1" bore for disc/drum and just bolt it to the firewall.

Re: Updating the 72 GMC
 

the hydro-boost can be mounted at the firewall. there is a couple of ways to mount it,

1972 GMC here also.

Re: Updating the 72 GMC
 

Way cool... thanks!

Re: Updating the 72 GMC
 

Sounds about right.....pull it apart for a few things and the momentum builds!

Re: Updating the 72 GMC
 

This feels right.......finished product should make you smile.

Re: Updating the 72 GMC
 

A little more progress.

Re: Updating the 72 GMC
 

Nice. I think I'm gonna go and over charge my battery tonight.

Re: Updating the 72 GMC
 

My current work-in-progress. Just fired it up this week!

Re: Updating the 72 GMC
 

That looks great! But that rusty master cylinder kind of attracts the eye. Any plans for prettying it up a bit?

Re: Updating the 72 GMC
 

Forgive me if I'm wrong, but I think that the master is a CPP piece based on the little sticker/logo on the prop valve. The masters come unpainted. I know because I just painted my new one after reading the printed color page included with it that tells you to paint it before you install it because if not it WILL rust. lol.

Re: Updating the 72 GMC
 

I reckon we will. We installed the Hotchkis front control arms and spring yesterday. Really nice kit BTW. I'll post pics later today. BTW I have the stock a-arms and after market sway bar if anyone close to me is in need.

Re: Updating the 72 GMC
 

It looks great. Can't wait to see the finished product.

Re: Updating the 72 GMC
 

I assume Point Harbor is on the coast ? I would take the sway bar but I had never heard of that place.

Beautiful build by the way :metal:

Re: Updating the 72 GMC
 

Great looking work! What size tire are you running?

Re: Updating the 72 GMC
 

Right now we have 265/75/15 on all 4 corners. But I'm thinking once we are done with this round of upgrades going with some 275's in the back and 255's in the front depending on clearance.

Re: Updating the 72 GMC
 

We have been picking away at the GMC but with the oppressive heat and getting our regular work out the door it is taking way longer than we would have liked. We did get the new hides mounted and installed.

Re: Updating the 72 GMC
 

Looks great! What size are the new hides?

Re: Updating the 72 GMC
 

The fronts are 255/70/15 and the rears are 265/75/15 all on 8" rims.

Re: Updating the 72 GMC
 

Alan, Your truck looks just right. If you don't mind me asking what brand of tires are they. Thanks, Randy

Re: Updating the 72 GMC
 

The fronts are Cooper Cobra GT 255/70/15.
The rears are BFG Long Trail T/A Touring 265/75/15.

I hated to mix the brands but this was the look I was going for.

Re: Updating the 72 GMC
 

Almost finished. Just got it back from the alignment shop.
