I have a 84 Mustang with a 351W and i had a 2bbl on it but just bought a 750 double pumper and was trying to figure out what jets would work best. Its been bored .060 over, .512 lift cam, stock headers cause i cant get others to fit by steering knuckle, Automatic and stock 7.5 rear. Been told a 650 would be better but i thought maybe a 750 would work with small jets but i dont know how to figure what size. Any help i would greatly appreciate. Thanks!!
