Looking for some sage advice. The engine is a rebuilt (by previous owner) Mercruiser, 5.7 carb 260. Not sure of the year of this engine as the valve covers have bolts on the outer edge, rather than down the middle.Came with a new starter,altenator,carburator, exhaust manifolds & risers. It has a Alpha One Gen 2 outdrive. I'm looking to replace the engine with a new or reman vortec 5.7 with new intake manifold and electric fuel pump.Will this be compatible with the newer parts off the old engine? They only have about 10 hours on them.I've looked at Michigan Motorz, Centerline Engines and a company called Marineengines4less.com online. ME4L has some good prices, but I can't find any reviews on the company. I'm currently leaning towards Michigan Motorz. Even thought about a 383 stroker, but from what I have read here, my Alpha One Gen2 might not be strong enough to handle the extra hp. Your expert advice would be much appreciated.
