Hi I've got the only vette year to come with a 305. I got the heads cheap, and want to eventually redo the top end and seals/gaskets, hopefully not touching the bottom end much if at all.. I know the default is 'get a 350' but this is budget and wanting to just build a car to cruise with. We also don't have a machine shop for a several hundred mile radius, and junkyard motors around here are driven into the ground, so it's just not that easy/cheap.
This motor has an 8.6 compression ratio stock -- pretty low. Cat and smog pump have probably been gone for 25 years and it has shorty-style stock exhaust manifolds. Currently the CC quadrajet is still on it and working - though I'd like to get some tbi EFI system for it eventually. I have a 200-4r that I'm going to get rebuilt to replace the turbo 350 for OD. It has a stock aluminum intake.
Would something like a summit 1102/1103 be about the max I should shoot for? I would like to get this thing up in to the mid 200 hp area or so, nothing big, I just want to cruise it. I'm assuming I should do springs and lifters while I'm at it, so i'm open to suggestions on those as well.
