best compression ratio street build?

right now i dont really know. i dont know what much of anything costs. im not goin to be building the motor for a while prolly, since i 1st have to get a paint job ect, on the car. all i know is i want my 360 and the 904 to be tanked, balanced and completly rebuilt. baiscally tryin to make whats old new again, but with better parts and there fore, better hp and mileage

you are on the right track, spending time doing research BEFORE spending money on parts is the key to any successful build, a 360 is an excellent engine with tons of potential, clean up the stock heads, good valve job, shoot for around 9.5:1 CR, and fuel mileage is more about HOW you drive than WHAT you drive
