How about the AMS JE specs piston?

 

I am tending to stay away from JE's at that horsepower level. They are not a strutted skirt piston like the Wiseco so they can tend to piston slap over time. Mine are good so far, but Luke has been through a couple sets. Wiseco HD for us from now on and definitely anything over 750whp. We run off the shelf Wiseco HDs in our 1G Eclipse drag car as does Kiggly in his 8 sec FWD 1G.

 

Thank John,i heard to that je piston having that issue..so some of my fren suggest wiseco or get ross piston...

 

anyone hve issue with ams je specs pistons
