Low compression small port. Looking for Caterpillar torque...............

Blake if I remember right we did a test of pistons and the Cast out lasted the Hyper on it....... I think if you can find either one it will work.....

Keith Black has a 1.350 with a 20.5 cc dish.

The FORGED Probe #12397-.030, 18.5 cc dish is a 1.250" compressyon height.

I may have to find two more 6.7 rods to make a full set, and go with the hypers Dave was talking about. I had rather keep the piston to cylinder wall clearance tight on this build, it's for my tow truck.

I have a set of 6.8's and a 4.5 cast crank for it.

You could run a 4032 alloy forged if you want tighter clearances. Not sure about other manufacturers, but Diamond will make any piston in the catalog in 4032 for the same price.

Randy could also provide you with a Factory Performance Series 4032 forged...http://www.probeindustries.com/Ford_460_24_4cc_Dish_Top_FPS_Pistons_p/p2404f.htm
