Just for fun. I was doing some organization in my shop and found the stock pistons out of the 340... Just thought this was fun to see the difference between stock 1.84" and the new 1.295" compression height pistons. I think I'll get a little bit of a friction benefit with the new ones. Also they feel so much heavier with the steel struts cast in and that massive skirt.

I'll be in the shop
Should definitely be more responsive with the lighter pistons. I just picked up my 340 block/rotating assembly from the machine shop. Went with new light weight pistons and forged I-beam rods. 65
Piston tech question...
Does a shorter piston tend to rock more in the bore?
If so does that cause faster wear on the cyl walls and piston skirts?

The taller piston will be more prone to rocking in the bore. The pin is lower so the piston above the pin has more leverage over the rest of the piston.
What's the weight difference?
723g for the stock piston vs 467g for the new piston.
Im pretty sure the h-beam rods, 1.2mm ring pack and .927 pins will also be a bit lighter than the stock stuff.
No, the shorter piston will rock more. If the piston maker gets it right, the piston expands at operating temp to close up the gap. The distance that the piston can rock then becomes the distance from the piston top to piston bottom. The longer the piston, the more stable it is.
1 Million grams…
