i have a bored out 30 over block stock cam. gt40 x alum heads roler rockers, gt40 intake full exhaust, underdrives and electric fan. what size injectors should i run? and do i have to change out the mass air sensor at the same time? future mods include med power supercharger.

 

24's for what you got now and yes you'll have to change your meter. When you strap on a blower you'll have to move up to 42's

 

thanks for the advise i didnt really have a clue what size to get and didn't want to go to big.
