Well fellas I started out on this build about 13 months ago and slowly bought all the parts for this 383 stroker to drop into my 72 chevy p/u. I'm finally finished with the motor, and when I ran the motor for the first time it sounded like a beast! I was using 93 octane fuel. Anyway, I ran My numbers through the desktop dyno and I believe that this is too good to be true so I'd like some professional opinions on expected compression ratios, HP, and TQ (for someone else out there who knows how to run a desktop dyno better than this dummy! I've included every morsel of info I thought would be pertinent. Any help is appreciated. Thank again guys and pics and video to follow!
