Jerry, the top end you did for me, how many hours do you suggest running before reringing and total piston replacement?

Dez I have a 87 top end done by Jerry and I get 33-40 hours MAX out of a piston.  Basically every season I need a new piston due to the skirt cracking. 

The one I just pulled has 34/35 hours on it and it has a 1/2 inch crack on one of the cut outs, no damage but it has a crack.

This is my 3rd piston on this bore so we'll see if I get a 4th or it'll need a bore.
