Old Guy with 87 GT · 02-11-2003, 08:15 AM

i got the chance to check out both compression ratio calculaters .......theres a few specifics that i'm not positive about with the new pistons though......i'm thinking it'll come out to around 9.4-1..... 9.5 -1 .....my pistons have a little bit bigger valve reliefes and i'm not sure of the ring hight

i'm going to see my engine builder tonight so i'll see if i can clear things up with the deck hight .....i'll see what i can find out and update ........2 million questions.........i'll probly ask three million by the time i'm done

thanks for the help
