~9.5-10:1 depending on your HG thickness if I remember correctly with P heads.

posted this inyour other thread as well

101.6 mm bore, 76.2 mm stroke, 9.0 compression ratio for GT40 heads

101.6 mm bore, 76.2 mm stroke, 9.1 compression ratio for GT40P heads

if there milled it would be slightly higher

thanks, that gives me a ball park as to what to look at stock. now to figure out what pistons to get lol

[Timido]

remember boring the motor .030 or .060 gives it more compression also if you are planing on replacing pistons and rebuilding
