I have a couple of questions......

1. What should the ring gap be for a set of pistons, when I plan on spraying 150-200 frequently, but upto a 300 shot?

The machine shop set the gap at .030 top and .016 second. This seems like an awfully loose top. What do you guys think????? Let me know ASAP.

2. The eagle rods I have are offset on the bottom. I set all the pistons the same way on the rod (this would make the smaller side of the journals face each other). The problem is that on one side the rod is centered on the wrist pin and on the corresponding piston (i.e. 1 and 2) it is a little offset on the wrist pin (not centered). There is nothing contacting the inside of the piston, and nothing is in a bind. Would this be okay....or should I make absolutley sure they are centered?

3. The pistons I had made (custom from Ross) do not come out of the bore. It was my understanding they normally come out of the bore .006-.007. This is going to reduce my compression. So now I have to mill my heads...would this be alright (I have TEA 5.3 Stage 2 milled .010 already), or will there be some consequence??????? To make absolutely sure they are not at zero deck (maybe they do come out) is there a trick where I can measure?????

Please let me know anything you can as soon as possible. If I need to get new rings, etc...I will need to do that tomorrow as it should be completely assembled then. Also if I need to fix the rods I will have to that (while I wait on rings)

Call up Ross for advice on ring gap per application.

Personally, I would set it on the loose side for sure on the top ring. If the ring package is stacked close together, I'de set the second ring a little loose also.

If Ross Tech can't help you, then call up JE pistons. They are on the ball and can give you further reference.

 

I called ross first and they said to set the gap at .022 - .024. My machinist differed and that is why I am asking what you all though.

Anyone else?
