If it is I'd sell them to someone who wants to run a blower... C/H 1.991 around 8.5 c/r "The Armies of our ancestors were lucky, in that they were not trailed by a second army of pencil pushers."

Excellent example of much needed information obtained! Moparts is better than a dang library sometimes.(Even with members that are in a pre annoyed and ready to pounce state) Keep old mopars alive.

I believe the 906 heads for motor have been shaved but not sure how much yet? Maybe this well help my low compression prob. I was hoping to do 9.5 to 10.5 ball park? Any input? This is in a 70 440 hp stk crank bored 30 over using a # 3 grind mr 6pk cam & 6 pk carbs. I may change pistons . thanks again

But I am good with at least 9:5 with the price of fuel:

I had them in a 440 with 906 heads and a .484 cam, it ran great. 6540826-IMG00148-20110320-2106(Medium).jpg (228 downloads)

As Johnrr opined, the OP was mistaken about them being TRW pistons and some knowledgable Moparts members recogized the number as a SP 440 piston.......nothing else to see here!

My 440-6 is running the same cam but I am at close to 11:1.....it runs on 94 octane pump gas, but I expect that it'll need a race fuel mix to get the timing right for the track.....we'll see. I just couldn't live with low 9's or less for compression.
