how many hours etc on the motor? what year is the motor?
all stock, untouched besides pipes?

It is a 2003, 175 hrs., and all stock except the pipes.

i was poking around for parts, but not much luck.
the porting would pick up big, i know what it does to big blocks we build for cars!!

Call Scott at Speed and Custom Marine in Quincy, FL. Phone number 850-875-0381. He has a 496 HO that was ran hot and blown up. Maybe some parts you can use. Tell him Craig gave you his number.

thanks for the info.

all i need is cam and computer?

My first engine in the ZT260 was a whippled 502 that made 760Hp on 93 octane and 800Hp on 110 octane. Top speed with 760Hp was 87mph and 90mph with 800HP. This was with a standard length mercury sportmaster 1.35 ratio and a bravo 26 pitch.

Hope that helps.

Been a while. Motor dynoed at 635hp/650ft lbs. torque. -2 shortie works well. 5000 rpms at 79 mph with 1.36 xr drive stock out of the box bravo 1 26. These numbers were disappointing due to cam selection mostly. So now M3 Procharger on the way.
