I forgot the carb,my bad.750 dp.Thanks for the help.So more compression,more gear,maybe more converter.Is there a converter that is recommended?A brand name?In my old budget built 78 camaro I went from a cheap Boss Hogg converter to a more expensive TCI with the same stall and it lost .2.Also if I went to an thin steel shim head gasket like .019 how much compression would I gain?And how well will this gasket seal?I really thank you all for your input.Anymore estimates on my E.T.?
