Hi All,
Does anyone have the table of combustion chamber cc's for specific SB heads? Specificly 78 2bbl 302 in a mustangII and 74 2bbl 351W from a Montego. both have auto trans behind them. How much would it drop the compression ratio to put the 351 heads on the 302? That used to be an old school type upgrade, but if it drops the compression ratio too low it is a waste of time. But the 351 heads do "FLOW".
