brianbronc Posted April 18, 2023 Share Posted April 18, 2023 Ford 300... I have read that running an EFI manifold is just as good as a set of headers to let the engine breath and cheaper. What is a good source for an EFI manifold? Brian Link to comment Share on other sites More sharing options...

Fordboy300 Posted April 18, 2023 Share Posted April 18, 2023 I’ve had both headers and now I have the EFI manifolds and honestly I couldn’t tell the difference in performance but sound yes the header definitely sounded better that’s the only reason I would go back to the longtube header.
