Re: Pistons for 440 crossram wedge

Paul,

Nice engine package! I think with your aluminum heads, you are very safe from detonation with 92 and would probably be well within the “safe” range with 91 should local gas stations not have a higher octane.

I had my 440 rebuilt with KB Hypereutectic pistons. The pin height put them farther up in the hole giving me @ 9 - 9.5 comp. , which means I need to run 92 octane. I think I can find the p/n if I dig around a little. I had the same setup as you, and with those 4:30 gears it was a hell of a lot of fun. I've since changed to 3:23 gears so I can do a little more cruising.

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?
