Gary, I'm running 906 cast iron heads. They've been cleaned up a little and some minimal porting work done. I had this engine worked on originally by a local machinist. I found his bill and he used KB236 pistons. And I did have a detonation problem, which necessitated another rebuild. I took it to Randy Beyers in Gretna, NE who is more of a Mopar guy for the 2nd one. In looking at the pistons he said the 236 pistons that were installed were a stepped piston and what the 1st guy had done was machine off the step. So what he installed was the KB237 , which is the same piston without the step. The top land had broken off of #4 piston and resulted in a pretty good dent in the cylinder wall so it had to be sleeved. I now have a 0.040 over 440.
BTW going to a Mopar show in Omaha today. Going to be good weather so there should be a nice turnout.

I am finally after 3 years getting my 62 Belvedere back from Chris Cline Racing on Monday.
Mostly modified the straight axle, finished roll cage, new Lexan windows and fabricated new guts in the doors for roll up windows, headers with cut-outs and set up chassis for the strip etc. No power train changes.
I have a reverse pattern 727 with 4:30 gears and the engine was rebuilt 3 years ago with purple cam, New Holley 2x4 crossram with Edelbrock Aluminum Heads, but the guy who did the engine work left stock pistons which I am told are .100 below deck.
Only item left is what brand and compression pistons I should consider.
I would like to do occasional car show and maybe 4-6 outings at 1/8 or 1/4 mile drags.(I need to split time at strip with my 65 Coronet Hemi).
Anyone with piston experience and suggestions ? Criteria?
