Using Diamante Pistons in the Dodge 3.0

I have a 91 Daytona with the 3.0 engine and I was looking to add a little more to the engine while it was in the machine shop this winter for a rebuild. Does anyone know what year pistons from the Diamante's that worked in the Chrysler 3.0? Also is the difference between the Diamante and Chrysler pistons the depth of the dish cut in the top of the pistons that increases the compression? Finally, there are 12 and 24 valve pistons available for the Diamante, I assume I need the 12 valves? Any help would be greatly appreciated.

I honestly thought I could get the higher compression pistons through any engine rebuild parts supplier, but I am only finding two options for the Chrysler piston rebuild kits. Pistons that are stock with valve reliefs and a piston without valve reliefs yet the dish cut is the same so there would be very little increase in compression.

Again, any help would be greatly appreciated!

Thanks,

Re: Using Diamante Pistons in the Dodge 3.0

If anyone is looking for these pistons I have found a source that carries std, .020" and .040" over bore pistons here in the states. Just note the over bore pistons are NOT decked to make up for the additional volume. I should have my engine back from the machine shop in a couple of weeks to begin reassembly with a set of .020" over pistons. Let me know if you have questions. I will be trying to get this engine to make piston to valve clearance with Crower F5365 cams too.
