Price reduced to $500 or trade (see last paragraph) 3.7L 4cyl Mercury Marine engine. Uses slightly modified chevy bellhousing pattern (i.e. you can use any chevy trans with a little work) and Ford 460 bore spacing and head. Everything except the block and crank are OEM automotive parts, mostly Ford. I bought it among a bunch of other cores from a marina closing with the intent of doing a mild rebuild and tossing it in my Ford Ranger. Traditionally this engine is swapped into hotrods with narrow engine bays. I cleaned it up, threw all new engine wear parts at it, Speedmaster aluminum head with a Cometic MLS gasket, built a custom 5qt oil pan because I needed better crossmember clearance (out of way too thick metal because it's hard to do a good front skid on a Ranger). Top end is 1.8 Eglin rockers, Ferrea racing valves with somewhat mild speedmaster springs. The idea was to have a decent cruiser that could spend plenty of time at 4-5k like Mercury intended. I reused the OEM cam since it's a fairly aggressive cam to begin with (boats don't need tons of low end). I have several options for exhaust including a pair of 460 stainless headers, a driver's manifold and the OEM marine exhaust log. The 460 driver's manifold or header interfere with the OEM starter. There is a gear reduction starter available that supposedly solves that but I was going to use the passenger side center dump header as that fit nicely and dumped out in a good place. The OEM marine manifold which makes a good turbo manifold if you cut the jacket off. Intake is an OEM 4BBL that has coolant flow through it for carb heat and a heat exchanger for the oil built in. I can dig up my record of the exact ring gaps and bearing clearances but it's basically gapped for boost despite me intending to run it NA and the bearing clearances are all within the factory range. Basically just lost interest in the project. What's left for you to do is figure out an accessory drive, figure out how you want to do the thermostat housing and probably some little stuff I'm forgetting. I have a billet block I was gonna machine to fit two thermostats and sensors/fan switches and a GM 6.2 thermostat housing but haven't gotten around to it yet. In addition to the manifolds mentioned manifolds this engine comes with a bunch of spare (new) valvetrain stuff, an SBF internal balance damper and pulley, a bunch of 460 valve covers and spacers (took me some trial and error to come up with something that worked good) three-ish more engines worth of OEM parts including two good blocks and cranks, a 2bbl intake and at least one 4bbl manifold in addition to the one the engine has on it. You absolutely could toss the stock alternator on, use the stock power steering bracket, stock oil pan, figure out a trans and rock out. I also have three mercury heat exchangers you can sell to recoup some of the cost, or maybe keep one for an engine test stand. Between the head, valvetrain, rebuild parts and all the other $20/50/100 stuff I have far more than the asking price just in the new parts. I could be convinced to straight trade trade for a not too worn out Ford 3.0 V6, the pushrod one, not the OHC one (yes I know you could go pick one up on car-part for far less than my asking price, no I don't care). I would finish the oil pan for free if a cash buyer was interested at my asking price.
