Frequently Asked Questions
Is this a complete fuel injection system?
No. It is the intake manifold. You will also need injectors, a 4150-flange throttle body and an engine management system.
300-260 or 7137?
Both are multi-port EFI intakes for the small block Chevy. The 300-260 also fits 1987–1995 heads and uses a 4150 throttle body; the 7137 is for 1955–1986 heads, has long tunnel-ram style runners and takes up to a 90mm throttle body.
