Default inejctors for a 408

quick question...what # injectors are you 408 guys using? will the 37# i have be enough or should i buy different ones? the guy who is buying my motor wanted to know if i planned on keeping them and i wasn't sure if they'd be alright.

thanks

well it would be a high compression motor with nitrous. i talked with texas speed about the cam motion 256/267 cam and that FMS godzilla cam also has my attention

as far as power...what do the 408's usually put down NA with a healthy h/c setup? 520 or so? i would plan on starting with a 150-200 shot

They will range from 440hp to 520hp or more depending on the car, dyno, and setup.

With your setup and also planning to spray I would go no less then 42# injectors. Ive got them on my car with racetronix PnP system and its made over 620hp with more left in them. The car never started running lean.
