Hey, I'm sick of my stock '84 Chevy 350 in my Blazer, I know the 4.10s will help, but I want some more horsepower. The engine runs well w/ over 30 lbs of oil pressure at hot idle and good compression. I know it's not just out of tune and I know it's not a bad motor, it's just gutless. Thinking Carb and intake Cam HEI Headers and exhaust I am thinking about this cam I will replace the timing chain and obviously the lifters while I am in there. I don't think I will need to swap springs though(I really don't wanna have to dig into the heads right now). The carb and and distributor are computer controlled, so those need to go. A buddy has a prejunk HEI that he said I could have and I am thinking about putting a Holley 670 Street Avenger that's currently on my Challenger on top of a Weiand Action Plus intake manifold a buddy said he would give me. as far as headers go... My buddy got a set of Hedman Elite headers for his big block Camaro. They are very nice heavy duty headers. I know everyone on here says to go with Thorleys but I want to stay a traditional 4-1 header. I looking in summit and all the truck headers in the elite series were like $270. There Ceramic coated too! They list half ton and 3/4-1 ton 4x4s as different though. Anyone know why? I'm eventually gonna put a Dana 60 in my Blazer, shouldn't be any problems though that I could think of. I heard sometimes the rear shackle can get close. Will my stock starter fit? I just replaced it a while back... Anyway, if anyone has run them or has an opinion, let me know! Thanks! Thinking a dual 2 1/2 inch exhaust with Flowmaster 50 series mufflers Eventually I want to build a Fuelie 383 but that's gonna cost some big bucks that I could definitley use elsewhere. Anyway, it's gonna got in my '84 Blazer that w/ eventually be lifted 2.5 inches and running 33s w/ 3/4 ton running gear(4.10s in the axles) If the cam ain't right, anyone got a suggestion? Cheap is good by the way.
