It can be mounted forward, backward, or sideways on our Victor EFI square bore (4150) style manifolds, when fuel rail or waterneck clearance permits. Because of its low profile, it will not fit Chevy manifolds in the forward mount configuration as it will hit the water neck. It accommodates LS1 80 mm or Edelbrock PN 3864 LS2 (90mm 4-bolt) or Ford style 75mm throttle bodies.
