I am getting ready to assemble a 540 cubic inch pump gas engine to sell (it was originally set up as a 572). I have unconfirmed 3rd hand information that it made 640 dyno horsepower, then got starved for oil in the boat after an oil line broke, so the crank and rods were ruined. The block was not damaged, and has been to the shop for machine hone with torque plate. The block is a tall deck, Dart block at 4.500" bore.
I plan to purchase new a new Eagle 4.25" stroke crank and new Eagle rods, of course all new rings, bearings, gaskets, oil pump, etc. The JE pistons survived as the engine was not run a long period after the oil problem started, or a new set of pistons could be substituted if someone contacts me prior to getting the assembly balanced, for example if you wanted lower compression for a blower engine, or perhaps higher compression to run with AV gas.
Heads are a set of Merlin rectangular port iron heads that were freshly done at Pfaff, identical to the ones that were on the engine. These could be upgraded to aluminum heads if someone so desired. This would include hydraulic roller cam, new hydraulic roller lifters, new roller rockers, and new polished valve covers.
Naturally this engine will be measured and assembled to my usual quality standards. Each bearing clearance measured, ring end gaps filed to fit, crank thrust set, oil pump disassembled and checked, camshaft degreed.
I will complete the engine to be used in either a jet or outdrive configuration with a single plane intake, 10 qt oil pan, and flywheel or flexplate as necessary for your boat. No carburetor or ignition at this price, long engine only, $10,700.
Any upgrades or additional parts would add to the cost. Note that I do have a real nice 12-71 polished Mooneyham blower for sale for $3800, but at that point I would suggest upgrading crankshaft and rods, aluminum heads and an intercooler.
