.030 5.9 magnum

The pistons have .030 stamped on top of them.. I have the heads off going to be pilling the pan this weekend.. this motor does not have over 50k on it. And if it does not by much. It got rebuilt and drove for a couple years and then swapped for a diesel. It was in a 95 dodge 2500..

As for tranny I plan on using the 904 that I have but rebuilt with a shift kit added.. the converter will be based on cam/motor build..

Like I said earlier I measured the piston to deck gap and came up with .085 which from what I read would put me in the 7 to 1 cr and I want more like 9.5 to 1 or 10 to 1. That's why the stock heads are going away and I was asking about pistons..

I don't know much about motors.. this is my first build and I want to do it right the first time. But I try to research as much as I can.
