What if you want to build your very own mega-horsepower EFI small block or big block from scratch in the quest for drag strip supremacy, and a factory EFI induction setup can’t live up to your horsepower aspirations? Try one of our 4150 or Dominator style 4-barrel throttle bodies and experience serious flow potential.

Every FAST™ 4 barrel throttle body is machined from 6061-T6 billet aluminum for superior strength and appearance, and features a host of desirable features for maximum performance with minimum weight and bulk.

Ever wondered how a 426 Hemi, 351C, or L88 rat motor would run with fuel injection? FAST™ has the throttle bodies to help you find out.
