Squirt hole or no squirt hole?

[MOPAROFFICIAL]

You run the pistons backwards, turn them around on the rod......however, that only applies to factory pistons whose pins are offset. The offset pin from the factory was used to help put a "load" on the piston so they would not rattle so much. Turning them around backwards "unloads" them and frees up a little friction and does have benefits. It's an old racer's trick. Modern performance pistons have the pin centered, so there's no need to run them backwards.

Yep, thats what we are talking about.
Notches to the back .

Back in the day......I would just swap the piston and rod assy from side to side.
Swap #1 into #2 bore, vice-versa.
Notches/arrows all to the rear.
Never swapped the pistons around on the rods.

Look at these pix of the right lifter oil gallery in my race block....

Talk about ruff.

My new Crower rods dont havev squirt holes but I should have enough splash at 7k.

Neither have we, read the thread again.
Swapping pistons off rods, thats the long way home.

This post has been interesting, a year or so ago I had a disagreement with one of frequent member advisors about where cam lobes got most of their lubrication. Could not steer him towards the crankshaft. I think that the aforementioned posts bare me out.
