When building a strip or street car, many of our customers prefer an engine that puts out the horsepower and torque to throw you back into last week! For this reason, stroker engines have become a very popular choice among our customers. With that being said, Proformance Unlimited brings you our turn-key Chrysler 408 stroker!

This beast began its life as a Chrysler 306 Magnum block. Once our skilled machinists and engine builders got their hands on the block, this motor was destined to install fear into others. Featuring an Eagle cast steel crankshaft, SRP forged pistons, and Edelbrock Performer RPM aluminum cylinder heads, this Chrysler 408 crate engine, putting out 450 HP, is certain to get you the respect you deserve on the street and strip.

From custom painted engine blocks to our exclusive March Performance serpentine belt system, Proformance Unlimited can supply you with the crate engine that you have dreamed of and others fear! With over 50 years of shop experience, you can rest assured that we are here to help design and build the engine combination that best suits your vehicles needs. Unlike our competition, we stand by our turn-key crate engines with a one year, unlimited mile warranty.
