Dyno tuned my 5.7 hemi hilborn today - 415 rwhp
Wow, 146 in a 40 year old car with the drag coefficient of a brick, that is beyond respectable. It sounded real good as well.
Sorry about the motor. I hope you get the problem identified and solved. The piston is an easy fix, but the bore looks a bit rough. :( Hopefully a quick hone and a new piston and you'll be on your way.
Keep us updated.
