Is your current Chevy motor tired and worn out? Are you unable to keep up with the Honda Civic owned by the young punk that lives down the street from you? If so then you are in need for a serious upgrade from us at Proformance Unlimited. With that being said, we bring you our Chevy 454 stroker long block! This is truly one badass motor that is a force to be reckoned with!

This motor began its life as a seasoned Chevy 454 block with little chance of putting fear into anyone. However, our skilled machinists and engine builders breathed new life into this 454 block to create the long block stroker engine that you now see. Featuring an Eagle cast steel crankshaft with a 4.00 stroke, Keith Black pistons, and Edelbrock Performer RPM aluminum cylinder heads, this Chevy 454 long block, unleashing 550 HP, is certain to create nightmares for anyone that crosses your path.

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.
