JE said not much info on the job. They did give the bore at 4.38 and a 1.301 Compression Distance. .990 pin.
Pistons have as much Dome as Valve relief.


I will have to CC a cylinder with a piston in the hole to figure out compression. May have to change pistons to Run Gas or E85.

There are aluminum rods but with a mirror I cannot find a manufacturer on Rods or Crank.

Got the Card Today and its like 790/745 w 1.7, 281/290 @.050 111 lobe separation.

Fortunately all is super clean and nothing broken. Prob need to start another post to discuss options with these parts once I figure out compression. I 'd like to use it in 72 Demon that always ran Race Gas.
