that's an interesting idea, I have 6.535 and a 4.30" stroke in my low deck 517, I Suppose if the piston skirts were dimensionally the same as a low deck 451 or 511 (1.32" CH slug) the compression height above the pin might not matter as far as rotational clearance, Heres a pic of my JE pistons and short block. I think my Compression height was like 1.30"

But if you are talking about like an OEM type six pack or TRW 11.5 domed slug.....I would say no way the skirts are way too long.

If you have the crank and rods already build a low deck or swap out the rods. if you have the pistons maybe sell them to someone with a low compression 440?

But if you're building it from scratch and you have to get pistons made anyway....It would probably work if the skirts are as I stated before.
