The first one on our dyno hit 1,206 hp and made more than 1,000 lb-ft of torque from 3,400 to 6,100 rpm. See that 427 cubic inch beast perform in this ad's video. Others may try mounting one of these superchargers on a stock block designed for half the power we are making. Good luck! Our build recipe has been beefed up by upgrading the block to a Dart…

LS swaps are the overwhelming favorite power plant in this genre. They are relatively easy installs and deliver great $/hp in a small, lightweight package. Aesthetics are subjective. For purists, the typical LS looks out of place under the hood of their 1960-something Chevy. This engine is intended to bridge the aesthetic gap while still delivering tons of power with the reliability of fuel injection. The air…

Actual pricing will of course depend upon options selected, so the final appearance may vary from that seen in the photos. As mentioned above,…

They sell it as complete a complete system thereby eliminating the grief of trying to make it work on your own. Our immediate thought was that we could build it using a liquid-to-air intercooler sandwiched in a Holley intake manifold. That would make it plug-and-play. No issues of how to stuff a big air-to-air intake under the hood somewhere. We liked what we saw and ordered one on the spot. We picked the 10-rib version over…

This beast can drive to the track and tear it up when it gets there without breaking a sweat as you'll see in the video. The foundation is an RHS aluminum block. An aluminum block compared to its iron counterpart transfers heat better and weighs 100 lbs less. While weight reduction is very helpful to drag racers, it's huge in road race and autocross for its effect on vehicle turning…

We kept costs down using seasoned GM block and heads that we have digitally remastered from top to bottom on our CNC machines. Both block main and head fasteners are upgraded to P1 Manufacturing studs. The crank we use is a stock-stroke, forged Callies Compstar with 8 counterweights. The additional counterweights increase overall stiffness by about 25% and reduce harmonics so that the crank does not want to flex as much. Bottom line is that the engine lives…
