Marine 454 MPI Fuel Injection

--------------------------------------------------------------------------------

Complete multi-port fuel injection system off of a 7.4 liter 454 mercruiser. This is a stand alone system. All it needs is fuel and 12 volts. The wiring harness, computer, ect is mounted to the engine. This is complete with everything you need to upgrade your 454 or 502 to fuel injection except for the distributor.

These units are very heavy duty. The are designed to run in hot, wet conditions. Much better than the aftermarket crap that quits at the wrong time.

I was going to run this set up, but I ended up buying a whole '99 mercruiser motor and will not need this other set up.

$1000

In wooden box the whole unit weighs about 110-120 lbs. I can ship it at your expense from zip 37830. This in near Knoxville, TN.

Is This For A Rectangular Port Or Round Port Head?

Grendel · 10-13-2004, 04:04 PM

I am interested as well.

This is rectangle port. However, some of marine motors had oval port heads on them with the same set up. I know it doesn't make much sense (rectangle port intake and oval port heads) but Mercruiser did it.

Let me know if you have any other questions.

Not interested, but isn't that setup close to the same as used by GM on the 502 Ramjet? I know they look similar. BTW, I have heard good things about this system, and for the money, a good option to a relatively rare 454 TBI system.

I'm not sure what the ram jet system uses. What were they in?

Grendel · 10-17-2004, 08:31 AM

DOes the computer run the distributor?

If so, what kid of distributor does it require?

treehuggerssuck · 10-18-2004, 07:27 AM

The computer runs the distributor. I have the right distributor for it. Everything needed is there excepter things like plug wires, distributor cap, coil, ect.

The 502 RamJet is a crate engine from GM. Try this link:

I read somewhere that the intake is the marine intake like you are selling. That info could be wrong, though. Does your system have a Mass Air Sensor?

treehuggerssuck · 11-18-2004, 11:21 AM

I've still got 'em
