The new SP350/385hp uses the proven ZZ4 short block and ads to it the Fast Burn aluminum cylinder heads for 385 value packed horsepower. With value in mind, the Fast Burn 385 uses stamped steel rocker arms and the same ZZ4 camshaft that powers thousands of hot rods.The SP350/385 is an excellent choice for the basis of a custom engine. Its strong forged steel crankshaft and forged powdered metal connecting rods have been proven to 500 horsepower. And its Fast Burn cylinder heads are hungry for a little more cam.
