Ok guys I am new on here. I had to part with a build before it was finished.
I still have the AMR 840 pistons and Cylinders. The cylinders have been sleeved and may still need bored but that can be done before they are shipped. These are brand new and still at After Midnight Racings shop.
These are custom pistons and was not cheap. I paid $625 for the pistons and Have like $550 plus the Brute cylinder in getting them sleeved and bored.
Here is a link that has more info about the pistons.

You heads will need to be sent to AMR to have chamber work done to run these pistons.
Anymore question just ask. These are like 13.5 or more compression and are for the serious racers.
I will take $900 firm.
