I used the TC 1930 Clevite Pistons, you need to have the Valve reliefs cut in them though any competent machinist can handle this process. The Compression distance is 1.678 so final deck height at 0 with the 3.58 crank will be 9.591 leaving the machinist to square deck it .009 or more if needed. You can clean it up for compression you want with the head gasket. Compression with these and valve reliefs at 5cc ends up right at 10.5:1 with 62 cc heads. I am using the INDY/RHS X heads no port work at all. Comp Cams XE284 Hydraulic Flat Tappet, Gear Drive, Mopar Performance Crank, Eagle SIR ESP 5140 Rods, Line Honed with main studs, Head Studs...Cometic Gaskets Should be put together in 2 weeks from today. I had all the parts laying around including the block. Need to keep busy in my mind. This one is just a hobby motor that I am possibly trading for a 69 Dart GT...
Here is a current link to these pistons. I used .030 over. These ones are .040 over.
