Well, our stock-block stroker 331 finally made it to the chassis dyno and we're pleased with the results. It produced 346 hp at 5,900 rpm and 343 lb-ft of torque at 4,700 rpm. This equates to a drivetrain loss of 13 percent-about 57 hp and 72 torque.

This 331 powerplant can be both an excellent bracket engine and a great street engine. That being said, we've got some ideas floating around upstairs, so you just may see it pop up again. We're thinking a set of Twisted Wedge pistons, a bigger cam, more compression, and a little tsst, tsst may be in order. Stay tuned.
