I actually let my machine shop pick my rotating assembly for me as I have total faith in them (Domhoff's Racing Engines in Harmony, Pa) I am not sure what the piston part number is but I will let you know later as I am stopping in to the machine shop today and I will see if I can get that for you. The crank is a forged Molnar and I believe that the rods are I beams with upgraded bolts and the pistons are going to yield 11:1 compression with 63cc Edlebrock RPM heads with up sized 2.05 intakes. I ordered the heads bare and I also allowed my machinist (Doug Dumhoff) to go with the hardware that through experience he would use.
The amount of time and money this is taking is killing me but I feel that after talking the advice of many of the FABO members and not going with crate short block that I've done the right thing.
