Home FAQ About Us
With the knock out punch of a big block in a small block package, this engine has become our most popular Chevy stroker. A huge amount of low end torque with a noticeable rump is the signature for this engine. Don’t let the numbers scare you, this is a street engine through and through with a little bad boy thrown into the mix. Check the specs and you will see that we held nothing back. Power? Yes! As you can see by the graph, this engine produces a very strong torque curve that is not only good for everyday driving, but for hot rodding as well. Add the polish package and a Billet Specialities Tru-Trac accessory drive system to make this gem a show piece. Excellent fit for street rods, muscle cars, or fast sport trucks.
