Compression Ratios

[C20-67_N_MO]

Okay for most street engines you need to have your engine below like what? 10:1 or lower right?

So what the balance on power vs. compression ratio and still have a good powerful engine and still be able to use pump gas?

I've got like .30 over 400 sbc forged pistons and have been told by my hot rodding friends that is going to be a dog and not have the performance that a flat top would have. While this might be true, the trade off seems to be pump gas vs. 110 octane race gas at 6-7 bucks a gallon, or face denation with higher compression.

But with 64cc aluminmum heads and these dished pistons I should be just fine at 9.9:1 compression ratio, right?

So I know its a fine line for a street/cruiser engine vs. what you guys deal with on your ultra high performance motors right?

So give me some kind of insight of what I should be looking for as far as compression ratio goes for street use.

Thanks!
