It's loud and fast, and ready to roar because it is powered by 383 Stroker V8/400hp mated to a 4L60E transmission with a stall speed converter, an 8.8 Moser rear end, with 3:55 gears. It has Eagle Steel Crankshaft 3.75 stroke, and so much more! Included is a full self-tuning ECU, 3.5' touch screen LCD for both basic and advanced tuning options.
