Compression Ratio

Dan the man said

I was going by what a factory stock 318 would have for compression from the factory. I was thinking that if I was to get a car with a bone stock 318 and it ran fine and didn't smoke what performance could I expect from it with a few bolt ons. I'm taking about a LA 318. Of course if it would need a rebuild then I would raise the compression ratio.

this is actually a solid plan. get something that runs and cruise it around for the season while you build something to drop in later.

more than likely you're going to find something that's already had a go thru and if has an intake and carb that's great! heck, maybe a cam and headers, even better!

if that's the case just leave it alone and drive it. resist the temptation it "make it yours" or mess with it (unless it's radically over cammed or carb'd) and save all the work and money on building another motor exactly how you want it.
