I was thinking the same thing. Probably more like $1000+ for something like that.
I can tell you to get to 8:1 on a 5.9 with iron heads is going to take a custom piston though.
I'm in the middle of doing a 360 with open chamber '308 heads, and I couldn't get the compression to 8:1 with an off the shelf piston.
The closest thing I could get was a Probe SRS series piston. 14.5cc dish, but even with that you'd need a crazy thick head gasket to get to 8:1
That's exactly what I am finding. A friend thought of going with a chevy piston and getting my rods bushed to the chevy pin size, but up here the machinist's want a small fortune.

Depending on what you want, I can have custom Diamond pistons made. If you go to a full dish design, then up to a 50cc dish is not a problem. I can even do a group buy if I get at least 5 sets of the same piston.
What kind of money are you talking about. By the way I won't be building this until the spring. Just trying to get my head around what is required first.

Are you trying to run this thing on pump gas? Even so, I wouldn't be afraid to run 8~10psi with a 6-71 at 8.5:1. You could get there with the Probe's that I mentioned above. The top ring is .320" down from the crown as I remember. So not a bad choice for a blower piston...
With a splash of race gas, you could run even more if you wanted to "turn it up".
Yes on the pump gas. This is going to be a street engine to replace my current LA/Magnum hybrid. A great working engine but I want the eye candy sticking out of the hood. Not to mention the extra thrills of close to 600 HP and TQ. Do you have a part number for that probe piston? I would like to check it out.
