Title: 390 FE
Post by: SuperDuty on February 14, 2010, 08:07:52 PM
So whats the deal with these motors? Anyone have a little history? The guy I bought the boat from said it was out of a 68 mustang. Iv noticed alot of people dont like this motor since I started trying to sale it. Any major issues with anything? Seems to run fine so far. Any other block interchange parts with it?

Perfectly fine motor.    Run her until 'til she blows.

X2,  nothing wrong with them.  There just small (displacement) for a bigblock.

Some specs, http://www.mercurystuff.com/fe-engine-specs.html

Put one, years ago, in one of my pops' old 1 ton dump trucks (I think it was a 77 truck, dunno engines year, but 60's I'm pretty sure). Thing ran STRONG for all the years he had it! Supposedly a "Police Interceptor" version, whatever that may mean, it did have a good lope to it's idle and unknown what the mileage was on it when we did this. Dunno anything about them, never did, just a good deal when we needed an engine.

Only sold it to buy another 5-ton truck. Moved around a 5500, or better, lb truck, with a 2+k load on it just fine. Empty, would lite up the dual rear tires pretty easily. I would think it would be perfectly fine motivating any jet boat.
