Here's the latest one to leave the bench. It's a local friends of mine. It was on the wore out side so I didn't take a before vid (wouldn't have been a fair comparison).

The piston was rattlin around like a marble in a paint can. The skirts were wore pretty bad.
Also is cracked right in the middle of the intake side. It wasn't gonna last a whole lot longer.
It was rocking enough to slap the squishband.

Yep, it was well on it's way to wreckin the whole thing. The wear on the piston was expected, but the crack wasn't (although I have seen them before). Just a stress fracture from slappin around.

To keep the ring ends from popin out the intake port.
I was wondering the same thing, considering the ring end pin is off to the side of the port, and the bottom ring drops below the hump anyway. Sounds good though

Looks like a great set up for some firewood. Nice sound and held really well in the cut. Nice job Stump

No second ring & the top ring pin is in the center now:msp_wink:

Just watched the video. This isn't going to help me decide if I should keep my 260 or my 361?!
Looks like you can gring a lot out of the jug... Did you alter the timing much? How about the ignition?

It'll really be nice once it's broke in. It's holdin around 11,000 rpms in the cut already.

Yep, the port timing is different than stock & the ignition timing is advanced around 8 degrees from stock.
