When building a strip or street car, many of our customers prefer a Ford small block that puts out the horsepower and torque to make women and children cry. For this reason, small block stroker engines have become all the rage. With that being said, Proformance Unlimited brings you our Ford 347 stroker long block monster!
This beast began its life as an ordinary Ford 302 roller block with little hope of instilling fear into society. However, our skilled machinists and engine builders immediately began to groom this docile Ford 302 block into the monster 347 long block that you see. Featuring an Eagle cast steel crankshaft, Keith Black flat top pistons, and Dart aluminum performance cylinder heads, this Ford 347 long block, putting out 425 HP, is certain to send many Chevy owners home crying to their mothers.
From custom painted engine blocks to our exclusive March Performance serpentine belt system, Proformance Unlimited can supply you with the long block motor 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 long block engines with a one year, unlimited mile warranty.
