Havnt been posting in a while but still been picking away at the car. Motor is almost done. Used a date coded block that came with the car. Nothing radical, but it has the stock rotating assembly, cant recall piston brand off hand but compression should be in the ball park of upper 9's. Cam is a mopar performance purple cam, and it going to run 452 heads with an original chrysler aluminum intake. Should be a tad better than stock anyway..
