What is it about late 60’s American iron that is all about massive? In a day of high gas prices and eco-friendly engines, excessively large motors are no longer being produced by Detroit. However, if you want the cast-iron excess of yesterdays, then look no further than our turn-key Pontiac 461 stroker crate engine.

Our Pontiac 461 crate engine begins with a Pontiac 400 block and an Eagle crankshaft with a 4.210 stroke. Using Edelbrock aluminum cylinder heads, our Pontiac 461 crate engine pumps out 475 horsepower. Since we adjust the timing and carburetor for optimal performance before we ship your engine, this turn-key 461 crate engine is ready to be placed into your Pontiac upon arrival.

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.
