Thread: FS 1 set of 523 CI supercharged/intercooled 700 hp motors w/ just dyno time

Tweet

I had built 4 of these motors back in 1998 figuring that I would break one or two in time and it never happened so they have sat till now.
Sold boat with 2 of these motors but held on to 2 of them in case I decided to buy another boat but, decided not to and sell the motors.

Here are a few pics of them and some info.
If you need more info and dyno sheets contact me at
choppo99@mindspring.com.
$27,000 for the pair or will split them up and sell just one $13,500
Plus xtra pulleys and belts and asst other related items.
Parts and machine work alone is much more than I am asking.
