Thanks QM for setting that straight.
I understood it as soon as I seen that diagram. Makes sense.
We kind of did it with the pistons in a Dodge 318 Ci (5.2L) V8 without moving the cylinders. The piston in all pre 2010 Chrysler small V8's had an offset piston pin so the piston had to c0ck sideways on the power stroke. It was done to make the engine quiet by making the pistons skirt tight on the cylinder wall, piston slap. BIG time frictional drag. But installing that same piston 180 degrees on the connecting rod, you picked up about 8 to 10 Lb/Tq in the lower RPM range. The net effect was putting the piston more directly over the rod and crankshaft pin on the power stroke.
On the exhaust stroke the piston may c0ck a bit sideways in the Forza engine but with no load it should be minimal drag.
