I don't think your going to find a manifold that will work with the rest of the Merc FI system. Is this what you have? http://www.perfprotech.com/mercruise.../180?model=507 You could try posting in the parts wanted section on boating forums or search the net for used ones. Or you could always chang to carbs. 2K for just the manifold section is rediculous. Thanks |

I know of 4 502 magnum MPI intake set ups, two are stock and two are ported.
The ported ones pushed a Cafe Racer into the low 70's, I would guess that would take 475-500 HP. Also have the cams and computers from the ported ones. The first thing you need on any of the BBC motors is a good exhaust. |

The manifolds everyone is replying about are EFI. Electronic Fuel Injection, The MPI means Multiport Fuel Injection. There are two styles, the older system used a lift pump that mounted on the seapump. The other style are the ones that have been pictured & uses a cool fuel electric pump mounted behind the seapump. The 500efi & 525efi are completely different. Which one do you have? Can you post some pics? I have both styles that I can sell. Randy
