Mopar purple .528 for a 383?

I thought I would update this thread for anyone interested, motor is out and torn down to the short block. I remeasured the piston deck clearance incorrectly before. I’m actually at .0965 in the hole, whoever rebuilt the motor used standard 383 pistons. I would only get 8.71:1 with the 74 cc chambers and .027 head gasket.

I am definitely bummed out, but I’m glad I checked it because I would’ve been more bummed with that big cam and no compression. Starting the search for some pistons to bump me up closer to 10 to 1.
