383 stroker on the dyno this morning. Couldn’t believe the torque this thing made! Wish the horsepower was a little more but still a torque monster. I’m calling it 500hp and 490tq. Overall really happy with how everything went.
Thanks again to Craig’s dyno and machine!

4 cylinder 2.3 Saab engine. Gonna be pushing around 400hp. Balance shaft delete. Bore and resurface.
