Here are the specs for a 10 hour engine that I'm considering:

Motor - 454 Fully Roller - carb to pan only no accessories

Carb - 1050 dominator

Rods - Cat h-beam

Pistons - Speed pro L2399F30 forged

Rectangular Heads - Ported at the chambers with 2.25/intake and 1.88/exhaust valves stainless steel with 1.625
isky tool room valve springs with titaneum retainers

The crank - Eagle 4340 steel cut 10/20

Double true roller timming chain

Meeling high volume oil pump, 70 to 80 pounds of oil pressure

Auminum timing cover and gill oil pan

What would you consider reasonable $$$$

2500-3000 tops, the carb you will have to sell, too much for that engine. The eagle crank, not so hot especially after its been cut, what cam? The pistons are worth 300, that what I use. The parts dont mean that much, its the machining quality and assembly that matters. Im thinking they didnt know anything about marine to put that big a carb on it.

yeah teh 1050 dom is too big. My 468 blower motor has a 1050 and many people felt it was to large for that.
