82 corvette 350
I have aquired a 350 duel crossfire engine out of a 82 vette. My question is how can I beef up this engine from its factory 200 hp rating and what is the most I can expect to get out of this engine without going into the bottom end and leaving the stock heads on ? I would love to build a kick but engine but I just do not have the money. I think the most I could afford is changing the cam and lifters. I also will be switching intakes to a 4 bbl. and using headers instead of the factory manifolds. What is the most hp I can get with these changes. Thanks

I have a 305 in my car now that has a rod knock but it also has the quadrajet carb and 4bbl intake. Also has the none computer HEI ignition and headers. So I am just going to switch all these over. I was wondering about the fuel pump though,on the vette is it in the gas tank or on the engine?

I believe the limiting factor on your '82 engine is the puny throttle bodies. You can add heads and a cam, but those injectors will not provide enough 'juice' to make good use of them. You can buy larger throttle bodies for that intake. Hopefully others with more knowledge can offer specific advice.
