The Engine Factory ( which Advertises on this site) builds a real strong engine, for the price. I have a 302 with 350HP, the car will scare you to death, when you get on it. I am not easy to scare, have owned a 383 Road Runner, 350 Nova, 340 Road Runner, 454 Chevy and several other so called fast cars, this Cobra is by far the fastest I have ever owned.
I think you can find their site at
