70Chevelle

im building a motor for boost but it wont be boosted right away.

I was going to try 2 acchive 10:1 w/ the 5.3 heads then put the 6.0 heads on to drop the comp back down when I get the turbo stuff. If i got the 10:1 w/ the 53 heads what would by comp be w/ the 60 heads?


Thanks

I can't remember quite right but it should be around the high 8:1 range with the 6.0L heads ( 62cc chambers 5.3 to 72cc chamber 6.0 ).
There is a really good thread here relating to this exact question. It is usually at the top of the forum. Use the link below and good luck! Keep us up on the build.
