The engine would have no hp with a 8:1 compression if l did that.l could bore it to a 440 and use standard 440 pistons which be The same price as those low compression 383 pistons are. Mise well bore to a 440 then get another crank it be about the same price.

That's sick what was the cost of them? Do you still have your 426 wedge specs when you had them made custom?

In theory, there is no difference between theory and practice. In practice, there is.

I've had to bore several 426 blocks, both street and M.W. blocks to 4.320 and used 440 pistons in them due to to much taper in the 4.310 bores, no problems on any of them I did have them all sonic tested first though boring them larger As far as strokers and lighters pistons compare to the stock stroke RB pistons weight the longer the stroke and the longer the rod the lighter the pistons get Can you say 526 grams with the pins

Hi All,
A true 426ci engine is a 4.252 bore.
If you go 0.062 over, it will be a 438ci engine...
Doesn't quite have the same ring to it?

I rather you use the 426 stock crank then get another one.ld rather not use 383 pistons either I faintly remember someone, years ago, who tried using oversize 383 pistons in a 426 wedge and they were either way to low or high in relation to the deck to be used The compression heights, deck heights, stroke and rod lengths are different on them
