Searching for EY707 or EN707 NOS pistons


Recommended Posts

Hello all,

I'm looking for NOS pistons that are 5" in diameter for restoring an old 1920's Wisconsin gas engine I have in my speedster.

I know nothing about EY707 or EN707 engines…all i read is that they have 5" pistons.

I'm planning on making them fit my old engine.

So if you have any leads or even just more specs about these pistons like wrist pin size and height, that would be awesome.

Even used pistons might fit my need.

I would also be looking for rings.

What year's truck can you find 707 gas engines ?

Thank you in advance.

If you can't find what you want, pistons can be made by Ross Racing Piston, JE Pistons or Wiseco. You can get the correct wrist pin location, pin diameter, skirt length, etc. for your application.

Hastings makes rings for a 5" pistons.


It doesn't cost anything to pay attention.
