Opinion on Clifford mods for Slant 6 motors

Dave Haertel said

What would that do for the rest of the build? Would that change which cam and lifters are needed, and what would I do with the head in that scenario, still just a port/polish? Sounds intriguing

No, the 198 rods are longer which would move the piston further up the cylinder. The 2.2l piston pins are located differently to allow for the longer rod to work without pushing the piston into the valves. From my understanding, its an alternative to milling a block so much that you have to start addressing pushrod lengths. It has the potential to increase compression upwards to 11.5:1 with no block or head mods.
