| Smeding Performance and Jenkins Competition have combined expertise to produce a limited-edition, higher performance version of our 572 Extreme. Bill Jenkins, using the latest in Pro Stock engine technology, has configured a special forged piston with a unique dome and a powerful new combustion chamber shape in the AFR aluminum heads producing a significant power increase to over xxx streetable horsepower. To compliment the new pistons and heads, Jenkins and Smeding collaborated on a custom-ground hydraulic roller cam for even more tire-shredding power. And as with all Smeding Performance engines, these pump gas powerhouses use 100% new race-duty parts, are all hand-assembled, and then dyno tuned and tested. Topping off this limited-edition mega motor is a special engraved plate with its own serial number and signed by Jenkins. |
