What pistons are currently available that would work on a stock stroke 400? I read about hemi rods and 451 pistons, but not sure what pistons would work for that combination.

A little background: I was in the process of rebuilding my truck's 400 and got a 383 crank ground and new bearings for it, but my project stalled. This was a few years before stroker kits became available. I'd like to use the crank I have, so I'm looking for new rods and pistons to finish the shortblock (flat top, zero deck is the goal). I'm likely going to be using Edelbrock RPM top end or better (Indy EZ top end kit).

This is going back in my '78 W200. I'd like to try out some of the local truck pulls with it again.
