What engine is this?!?
I have an unknown engine that came partially disassembled in a 271 fastech I bought. All that was left was the short block with seawater pump, crank pulley, circulation pump (all mercury racing blue) and a blower pulley (black) on the blue crank pulley. Those two locked together and had one set of bolts going through both.
Also has fuel management system from Aeromotive on the bottom of the motor, braided stainless for fuel and oil lines. and a vortech engineering oil line from the back of the block.
So at first I thought maybe a 500efi with a vortech supercharger?
Then I find the 496 bell housing (which formula confirmed it came with) and figured he just put the pretty pulleys on for show.
Pulled the engine tonight and took it apart and found this:
Block 8.2l stamped 10237300 and K30 on both sides MK9 behind flywheel.
Pistons: JE 755D Large single depression covering most of piston.
Rods: Eagle H-beam stamped M1 09 and another changing #
Arp rod bolts
So now I'm thinking 575sci ???

Boat tech: no mercruiser plate anywhere.
Griff: I was starting to think that too, but the factory mercury racing pulleys has me thrown off. I know you can buy them....but why $$$
