496 cu. in.  "STROKER" By JOSS ENGINES

Bryson's Truck

1983 GMC Sierra Classic

The new engine dynoed at 629hp @ 5900RPM
First time out  12.8 sec.

Then we added a new air gap intake and 1050 dominator.
Best time 12.3 @ 116mph (Not Sportsman Class Anymore)
We couldn't keep belts on the engine so we added
March pulleys, electric water pump, and electric fans.
Should have a few more ponies
