Thanks for this Thomas. I am very unhappy with the guy who rebuilt my engine. He did a number of questionable things and it is quite possible that he made a mistake with the piston specs. In fact I think he saw me as an ideal opportunity to experiment with engine mods that he had wanted to try out at someone else's cost. I regret agreeing to the modifications and wish I had only sanctioned a less ambitious rebuild.

That said, from memory the compression figure for each cylinder were good. When I have some time I will list the piston and ring specs along with the rebore specs and perhaps you could ask your Chrysler guru for his opinon. It is something I would like to resolve when I can find the time.

Regards,
Kevin
