rod length doesnt change cubic inches, piston size does, are they standard or oversize?

They are 30 over just didn't know if they are for a 350 or 400

Quick search on google shows this:

350 1/16-1/16-3/16 6.0 rods 12.1:1 TRW Forged L2509/10F*8

That is the intended purpose but could be used on different stroke depending on rod choice and deck height.

i think w/ a 3.75 and that compression height/rod you can get a 383 around 9in deck
