my friend screwed me. i told him i wanted 10.5 to 1. well he told me it was going to be 10.8 to 1. i did the math and it's 11.8 to 1.

flat top piston above the deck .015
.051 head gasket
61 cc head chamber
around 7-8 cc for the valve reliefs 540/560 lift. 2.10 intake 1.65 exhaust
36 quench

11.8 to 1


unless he messed up when he ordered the piston and got them .015 in the hole. but that would really mess me up. i'd have 10.9 to 1 but i'd have a quench of 66

i've got to get the oder # so i can check with venola to make use they come out .015 above the block. if they don't i'll have to change the head gasket to a thinner one. so i will still need race gas.

i live on port richey. does any gas stations around here sell race gas?
if not i need to know where i can buy 55 gal drums of race gas.

thanks for your help.
