Embarking on a restoration... - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Hello everyone!
I am new to this whole message board thing but the information I have seen since joining yesterday is awesome.

Last year I acquired a '72 GMC C20 "2500 Super Custom" Custom Camper from my Grandfather. He was the original owner and the truck is in beautiful original condition (except the new 454...beautiful but not original).

It even came with a fully restored '71 Teardrop camper!

Anyway, I have started some minor restoration to recover from 31 years of use and I have two questions:

1. Has anyone had an issue with the brake pedal squeaking?
It seems that a grommet or something is rotted out on the firewall.

2. Since the 454 was put in, the front rides very low compared to the rear. The truck originally had a 350. Would HD springs fix this? What brand do you all suggest?

I love seeing the pics of all the trucks and I will post some of mine soon.

You're probably right about the brake pedal squeak.Any of the vendors on the board should be able to hook you up with the bushing.
The 454 is probably a bit heavier than the smallblock that gave up it's spot.Add to that the fact that you're riding on 30 year old springs and you probably have some sag.Many of the vendors carry suspension parts and most should be able to hook you up with springs.I don't know if there were different springs for BB and sb engines in these trucks but there were lots of cars that used different springs depending on options and engines.
BTW welcome to the BB.

Welcome to the board. If you didn't live so far away, I would be glad to do a straight swap of my tired oil guzzuling "original" 350. For your gas guzzling 454

And yes, the big block trucks used heavier duty springs up front. You can always lower the back end, to give it a level look. Someone on the board mentioned that if you add aluminum heads, manifold and radiator. You should be back to Small block weight bias. But then,I could be wrong.
