Jack is still alive and doing well. There was a picture of him in the last Line Chaser (MSRA) at the Torquers reunion. There still is a "Jack Wheeler Racing", but he has nothing to do with it. The only Gary I know is Gary Hedden who was a partner of mine in a C/Dragster. I think he builds superchargers now. I use Hedwerks here in Bloomington. Boat motors are a lot like stock rather than a racing motor with 14 to 1 compression, and close valve to piston clearance. A good balance and roller cam, with a good set of heads will make a good boat motor.
