Another bogus hp rating.

Most small-inch Comp motors, which don't make a lot of torque, don't have to move 3,000-lb.-plus Stockers. The Three-Valve head may flow a lot, but it is still a 281-inch engine and won't make anywhere near the torque of an LT1. A good LT1 make 480-plus hp and 450-plus torque. Anyone who knows how to build a Stock engine knows how important torque is and without cubes it's hard to make torque.

I would guess that 375-400 hp could be achieved with the Three-Valve CJ engine after some R&D. Greg, I would say that a good Stocker engine has to make more than 1.5 times the factored rating to be above average.

The Stock Three-Valve at 300 is a joke and is not competitive. Not NHRA's fault, but people will have to run it and invest in a program before the rating can come down. This engine is very efficient from the factory and will not respond like many other engines. I'll agree that the 235 rating on the CJ version might be a little light, but not by 75-to100hp.
