WTB: 496 HO cams and ECU
 
Looking for 496 HO cam and ecu for 2 motors and engine covers later models. Or aftermarket cam that has gobs of torque down low
As I usually never run the boat above 3800 RPM with a few 4000 RPM peaks. This is a cruiser.

Rebuilding motors probably switching pistons , valve springs , roller rockers. Factory valves intake block etc.
what can be done to move factory HP and Torque curves down. This also a repower that I bought 2 used drop outs. Previously had
Mercruiser 340's

Just buy it all from Raylar. It is a tiny bit better than stock, its new and his roller rockers have the metric nuts and fit under the valve covers. Then send your ECU's to Whipple for stage 2 or 3 reprogram.
