Piston Question

I found a set of 428 .30 over pistons/rods
I want to purchase them
If Im correct (memory fails me sometimes) the 428 is the same bore as the 390 right?
If so I am snatching these bad boys up.
Please let me know

Nope, they are quite different. The stock 390 bores are 4.05"dia, and the 428 are 4.13"dia. Chances of being able to use the 428 pistons in a 390 block are slim to none.
