He’s not going to get very far with only one piston.

Nate S mentions .080 over 413 pistons. If they are truly available (i am NOT questioning Nate, only the supplier) they would be .017 over for 426 wedge. As he says, if your bore is good, they might clean at that. After that, you either will have to go custom, or .070 to standard bore 440 pistons. I have a 426 max that ran fine at .070 over. It even ran pretty good with .060 over 426 pistons, but with a bunch of piston to wall, it was noisy.

I would bet large that those are solid dome pistons, you could mill or lathe the domes off.
Kinda depends on how bad you want 426 pistons.

Thanks, I stand corrected.

If it’s not going into a 64 or 65 B-body why not go with with a 440 to start with?

If you mill the dome off they will no longer be a considered alcohol pistons?do not need alcohol ones need pump gas ones,these are useless to me.as another member said these pistons are ****

If you had a choice would you rather build a 426 wedge or another 440? Remember 426 pistons are expensive and right off the bat you would gain 14 cu. in. going with the 440.

If were shooting opinions lol, if i were him, i'd set aside the 426 block for now and find a 400 to stroke for that Duster, fer sure!!

You can NOT 'turn down' Forged Pistons like on a Lathe for example because:
* Forged Piston Skirts are OVAL.. designed to expand and become round at operating temps to fit the Bore !
This oval factor is built into them and called "CAM GROUND EFFECT" and the thermal expansion to 'round' at operating temps is mostly controlled internally by the I-Beam Pin Boss structures
FORGET THIS LATHE GARBAGE !
This is NOT a cast piston built in 1932.

You can still purchase a "std" 4.320" Bore ICON Forged Piston & std 5/64" inexpensive Rings.... Part #9953...which is a .070" over bore for your 426 (4.250" Std Bore)
https://www.summitracing.com/parts/uem-ic9953-std
Forged Pistons $551.
E424K Moly Rings $69.
This is your best and cheapest option
The ICON IC9953 is also very light,
and I would suggest Balancing is mandatory as you really have NO idea what target Bobweight was used in your 426 Crank ? and even if it is a 426 Crank for 100% positive ?

That's boring it to a 440 which l may do.it should be the original 426 crank.

If you map the taper and ovality of the unaltered piston a good CNC lathe can take off an even .010 or so all around. We'll leave the 1932 pistons to the 1932 lathe. At some point, depending on the shop you find, it may just be cheaper to go custom. There's no magic to this stuff, just details to comprehend.
