I have a pretty bad oil leak on the back of my intake, so since I have to pull my manifold anyway, I'm thinking about going ahead and tearing off my heads at the same time to try to get some decent power out of my motor. Here's what I have right now.
-small block 350
-demon 650 carb
-performer rpm intake
-longtube headers
everything else is stock, so i would presume it's the same specs as a 78 camaro, which means a compression ratio of around 8.2 to one. Unfortunately, I have no idea what the specs are as far as combustion chambers or piston dish sizes, though.
I'd like to get that up to a much more respectable ratio but still be able to run on 89 octane gas. I'm fine with iron heads, but would like to go aluminum as long as they're still affordable. I'll also probably go ahead and swap out my camshaft to match the new heads better. I'm also considering swapping to an air-gap intake.
I also was kinda thinking of going with really small combustion chambers, like 54cc, to really boost up my compression. Can anybody help me figure out how high my comp ratio would end up being if I went this route?
otherwise, can anybody help reccomend some heads and a cam? I'm not looking for crazy horsepower, just a nice jump from the 200-ish i have now. It needs to be mild mannered and very streetable, still.
