Post subject:  Engine Cylinder Specs and related shhhhhtuff...

Im doing my first engine rebuild. Bought a used 2004 3.7 engine.

I do have a bore/cylinder gauge to check all points of the cylinders.

What are the engine cylinder specs for a 3.7?

At what diameter size do I go with an oversized piston ring?

At what point do I go with an over sized piston?

Im just asking right now...as far as I can tell the cylinders look good except for 1 and 2 they have a small ridge which I will remove with a reamer.

Thanks

Oh man.

I have always wanted to do this! Dreamed about it. But never dropped the hammer.

I'll be watching this. Keep the updates rolling please :)

The bore and stroke etc. are all in the factory service manual if you have one. If not I'm sure you can find a PDF version online..
