Gary Thomas 1968 Pontiac FireBird 400 Stroked to 461ci Engine Dyno Pull
1968 Pontiac Fire Bird 400 AwesomeEngines® CNC Race prepped block to 4.155" Bore, new Mahle Stroker 10.25:1 Forged Pistons, AR-6.700 H-Beam 4340 Rods w/Scat 9000 Series Crankshaft all balanced up here @ our facility. We instaledl new Manley 2.11 stainless steel valves along with the 1.670 Exhaust to pick the heads up with a real rolled radius valve job. Installed Comp Cams BeHive Killer valve springs and light weight retainers to handle the .575" Pro Street Hyd Roller Custom Grind from Comp Cams to round out the short block. Manley push rods, PRW 1.6 aluminum roller rockers operate the opening and closing of the valves. The engine is a beast and your mom could drive it because of the idle quality and throttle response The actual HP numbers when I went back to look were 477Hp @ 4800 rpm and a whopping 597lbs of torque @ 3200 rpm and the power band actually was the smoothest and even I have ever seen. I quoted the 453 from the previous pull. The bsfc were .390's with a AFR of 13:1. The average torque was 565lbs all the way threw the pull. With the stock Dual Inlet air cleaner and the stock appearance of the engine, this is a very economical way to just run away from most on the street with a set of sticky MT Drag Radials. We now manufacture a 515cu 455 or 400" base block stroker engine with the exact same combo for an automatic car with over 650lbs of torque and 550hp for the Monster Pontiac Pro Street engine. Give us a ring if you want to have your Pontiac Engine put back to monster torque and hp numbers like these. Gary Thomas was the owner in the back ground and has owned this car since he was 20 years old. Can't tell you how old he is now but its well over 60! We did a complete restoration from ground up and shot the car with the paint to make it look brand new. We are installing A/C as well as complete chassis upgrades to handle this power.
