Just a reminder: Our 550 HP engine will remain available until GM stops supplying 502 marine base engines, (which could be anytime now) They now are sold complete from carb to pan, dyno run brand new for $8900. This has been a very popular engine, so if anyone has any interest contact me soon..

Bobby - Blue Lightning (203) 622-6343 or (203) 912-9550

When GM stops supplying the 502, wheres Merc going to get motors to build the 500,525, and 575 from?
OBTW that sounds like a nice price for that engine, I assume exhaust is seperate?

i though Merc bought tooling to make the 502 block and they were goign to manufacture them for themselves.

Good question!! Puder are you correct?

So that means the price of a 502 long block just doubled!

I knew mine was good investment.......

GMPP Division bought the tooling for the 502.

i knew it was somethign like that
