This kit is best suited for engines that have already been modified with headers and gears. It also performs best with a torque converter rated for a stall speed of 2800 RPM or higher.

Does this kit include everything needed for installation?

The kit includes the camshaft, lifters, assembly lube, and decals. It's recommended to also have a new oil filter and appropriate engine oil on hand for the installation.
