I have a friend "me" that has an engine that has one piston with a broken skirt.

I was thinking about cutting all the skirts off & sticking it back together & try it.

The skirts would end up being only 1/4 inch long....these are stock pistons for a 305.


Do you think the rings would seal at all with such a small skirt? It would be run around 6000 rpm.

this is just an experiment "fun cheap idea" & its just a 305 so I am not trying to kill a good block.


any comments?

I would think you would have a hard time keeping the piston from rocking in the bore and dragging really bad or getting wedged in and breaking.

Do you still have the broken piece? You could try JB welding it back on!

I work on high end imports and the factory race engines that are high reving small displacemet have very small skirts on them. They are noisey cold but once they warm up its ok. Not sure "I" would cut them off but I have seen more unusual things!

New piston for a 305? Naaaaaaa...

I was just wondering if anyone tried this crazy "stoopid" idea before & could tell me the outcome.

I think dirtbuster knows what will happen...I still might try it tho!! LOL

maybe we should guess how many laps it will make?

Depends on how many RPM's you run? I sold a guy a 305 years ago and b4 he put it in his truck he pulled the pan of and the was about 7 piston skirts laying in the pan. I dont know maybe its common for 305's running lots of R's to do this, or maybe there so worn out that the piston is twisting in the cylinder and breaking them lol. Anyways he put this motor in anyways and drove the truck from northern Minnesota to southern Texas. made it all the way. Said he drove it for 2 months before a rod decide it was time to venture to the outside world. I bet you'll make the whole night (notice I didnt put any money down on the bet) lol. Good luck.

You need that skirt to hold the piston straight....there's a reason its there..unless you want a busted bore wall....Id say go for it!!!!

Get a pool going. 5$ to get in. maybe you can raise enough money to build your new engine, or at least get started.

Not sure if i can get enough betting people interested in that idea TEAMPCR.

But it would be a good way to make a few bucks if I could!

It probably had excessive piston-wall clearance to break in the first place... cutting the end of the skirt off (largest part of piston) will probably make the largest portion of the piston .003-.005" smaller than it was before, which was already too small. My guess would be it will smoke like **** , foul a plug or run out of oil, then yak in catistrophic fashion.

Not sure it's worth a $11 piston and $25 gasket set to find out though.

If you got a good bore,it will be ok ,but will not live as long. I had a buddy who turned all of his down. Most good racing pistons have a short skirt.
