Actual compression ratio with 440 with flat top replacement pistons

sounds like me. building a 67 Bel 1 , dropping in a low compression 400! I figure it will give me 10X in fun for what I have in it!!!!

Best car I ever had was a 1963 Dart that was gutted and had a 340 and it ran 7.90 in the eighth mile and cost a grand total of $750
