Got a set of JE 2618 forged Pistons, dished. They're a custom set made for a finish bore size of 4.043, that includes piston to wall clearance that JE recommends. Pistons, rings, wrist pins, and spiral locks all brand new $540 shipped to your door. Below are some pics of the Pistons and spec sheet

Stroke and rod lenth they are made for? I'm guessing 3.900 stroke 6.125 rod and have it down in the hole .010" on a standard 9.240 deck?

This is what's on the box, so I'm assuming a 4" stroke and somewhere it says a 6.125 rod

 

I'll. try to get in touch with someone at JE tomorrow and ask them about the part number

 

Here's the other info that was on the box

4" stroke would be 1.115 comp height and yours is 1.150 kind of an odd ball setup. Not giving you a hard time or nothin just trying to figure out what ya have. May be for a different deck height or something. Glws

 

Thanks, I'm still learning about all those measurements! What stroke and that compression height would put it at a zero deck height?

 

Idk I know the aluminum blocks have a different deck height but dunno what it is off hand I suppose someone could have done a 3.900 stroke on a sleeved aluminum block like an ls2 or a ls1 even. I say sleeves because the factory liners wouldn't have really much left for thickness. Or I suppose someone could have been doing an aluminum rod setup and needed the extra deck clearance for rod stretch.

 

Okay, thanks! I'll see what JE can tell me tomorrow

 

Talked to the kind people at JE and here are the specs for the Pistons... 1.150 compression height, finish bore of 4.043 this includes piston to wall clearance, 6.125 rod length, -29cc dish, .927 pin, and 3.875 stroke....

Also open to trades on these! Thanks
