383 Stroker Dyno Session 450hp 479 ft lbs torque!

Chevy 383 Stroker. AFR 195cc eliminator heads fully CNC ported, Mighty Demon 750 Carb, Weiand Stealth "Air Strike" Intake Manifold, Comp Cams Extreme Energy 284 Camshaft, Stainless Steel Roller Rockers, Bad Ass "383 Stroker" Cast Valve Covers, Cast Chevy 400 Crankshaft, Forged Speed Pro 383 pistons, Eagle I Beam Connecting Rods. This is my first video Ive ever made, so sorry if it sucks. Had to trim it down from 30+min long. And I didnt even get all the pulls in. Made a total of 9 Dyno Pulls that day, with a result of 450 hp and 479 ft lbs. On the later pulls I had him turn the Dyno down to read as low as possible, which is 3000 RPM. By 3k it was already making 430 ft lbs! and at 6000 was still at 412 ft lbs, VERY flat and nice torque curve. We tried different size jets, 2 different carb spacers, and played with the timing. Best result was out of the box jetting for the carb, and carb right on the manifold! Lost 15 ft lbs on the low end with the carb spacers! Was a great day at the Dyno shop, hope you guys enjoy the video!
