So installing pistons and rings and all today but as i was i made sure there was no cracks or scratches of any kind in the pistons.

But as i got to my second to last one i found a small crack on top of the piston. so to check to see if it was bad i ended up breaking a small chunk off.


So i dont wanna spend 200+ on pistons so im hoping to find a single piston online somewhere but Summit/jegs/or hughes doesnt sell single pistons with 1/16,1/16,3/16 grooves.

Does anyone know of where to look.

P.S. I never called hughes due to they are closed so i only looked online and dont know if i can get them to ship me a single piston

 

when i bent my rod i went to a salvcage yard and they had an engine that was already torn down and i got a piston and rod

or your local dealership if you want new. if you are fine with used, I'd so as dakotas ram suggests and hit the junkyards. I would sketch a pic of the piston, take measurements with a dial caliper around all necessary spots on a good one, and weigh a good one if possible. Then go to the yard and pick one that fits your engine the best. Measure it and weigh it on the spot.

Usually pistons are almost always the same weight, and you end up balancing rods, not pistons. But you want to be sure. You want it to weigh the same as all the others to the gram. When all that rotating mass is spinning around in there at 5000rpms, a small imbalance can really be a problem.

If the piston is a little too heavy, you can grind a bit of non-essential metal off. too light, and you have to grind all of you other pistons to match, which I would not do, as they are already balanced to each other.

 

you looking for a stock piston i assume i got a whole 5.9 in my garage its a 96 block i can sell ya piston and rod out of it. im building my 408 so i only need the block.
