I ran this calc off butler’s site, assuming I use their copper .093 head gasket. Are my figures correct?
If so is 11.18 too high for pump gas, and would a 108 LSA cam help this deal be more pump gas friendly? (have not selected a cam yet)
Have a 3.36 rear and continental converter “should flash 2800-3200”.
Thanks all

I have two pump-gas motors without any issues at all sreet-strip cars
One motor is 11:98:1 comp with a 106 LSA and a 11:7:1 comp 108 LSA
First one is Eddy-heads the second is Speedmaster-heads with a tunnel ram.
I drive these cars alot and race almost every weekend. I posted the
dyno sheets on another page I think in the race section.
