Well just bought my dads 1981 GMC High Sierra. It has a Quadra-jet carb on it right now. I does have a mild cam in it as well. Not sure of the specs on the cam thought.

What shold be my first mod?

1. Long Tube Headers and Tru dual ehaust w/ x-pipe
2. Polished Intake & Carb

30 people have read this post and no suggestions come people post up. Anyways I had to spend 700$ on the rear end of my T/A so no major mods for the truck right now. However I did order a dress up kit from Summit. Nothing special.

 

hey, i would do the exaust first then do the intake and carb that away when that is done you dont waste time waiting around to get it out of the shop the carb 0and intake piece of cake then you get the reall sound quality instead of wondering what it would sound with the new carb and old exaust especially with headers. that is going to be awsom. i want to put headers on mine. i have a 90 chevy silverado k2500 shortbox extended cab 4by4 350 auto. i fabricated the exhaust my self. cut the muffler off. factory had to where 3 inch pipe into 4inch cuppler.then coming out 2 half inch to tailpipe. did away with that. i went 3inch out from 4inch coupler then split single to duel.used header pipe to weld 4inch in tip to where the bolts would be. the tips are 5 inch out. 2 cost me $80 at a hot rod shop. they wanted a hundred. that was a good bargain. they rumble. thought about a cherry bomb to add, but then it might sound like crap. good luck with your project keep me posted. later
