Here is my 98 vortec 5.7, it bolted right in. Had to have the pcm reflashed to take the vats out of it. Had to use a high hump so the 4L60e trans would clear. I even took the rear end out of the 98 truck and welded perches on so it would have the same gearing and new brakes. Oh and took the inside wire harness out of the 98 and installed in the 68.
