So I was dumb enough to let someone else change my oil on my 86 Chevy Stepside when it was twenty below zero here and that is where the trouble started. They didn't tighten the oil filter up, and about two weeks later I threw a rod through the oil pan. Now I want to rebuild the 350 and was looking for a few pointers. I have found a machine shop here in akron that can bore it out .30 over for me for a very good price, but was wondering where to go from there. I don't want something extreme, so a super high performance cam isn't what I want. I just want to beef up my truck and get it somewhere around or over 400 HP. Before this I had about 330. What I have in it now.... 350 out of an 85 Suburban original 4 speed manual tranny Quadrajet Carb Summit Headers with duals 4" lift suspension lift 33" Mickeys My main question is do you guys have any tips on what carb I should get and what cam I would want to buy. I looked into carb and intake kits from summit and they are 600 cfm carbs and intakes for about 350 bucks. I really dont know what kind of cam I should get. Any help is appreciated guys.
