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
