    I'm still up in the air about what to power my 25' Luhrs with- I already have a Chrysler 440 that is ready to drop in. I am however still thinking about dropping in a fairly "low priced" diesel, i.e. a 6.2 or 6.5 Chevy diesel in it's place. If I recall correctly, don't the Chevy diesels have that same flywheel and exhaust manifold bolt pattern as the standard small block Chevy?

    Is this even worth doing, assuming that I could sell the 440 for a few grand and build up the gm block? I only go out maybe once a month (it's a wife thing...)

    Thanks!

    Stick with the 440. Your not useing it enough for a diesel/gas payback, and you will be back in the water sooner with the engine you have.

    No 440 , even rebuilt is worth a "few" grand.

    Unless you are out on the water over 200 hours a year , much of the time in high RPM , high speed mode , keep the gasser.

    The winterizing , special oil and extra fuel filtration all add costs to diesel operation.
