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 turn-key 347 cubic inch Ford small block monster! This beast began its life as an ordinary 302 roller block with little hope of instilling fear into society. However, our skilled machinists and engine builders immediately began to groom this docile 302ci block into the 347ci monster crate engine that you see. Featuring an Eagle cast steel crankshaft, Keith Black flat top pistons, and Dart aluminum performance cylinder heads, this 347ci Ford small 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 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. |
