99/06 Hemi is the pro stockstuff. And parts on not as easy to come by as they were at one time. D7 has a couple of them competitng on occasion still. Usually in the lower 499" range. There is also the P5 stuff which was pro stock truck stuff and its even harder to come by, and is a SB. Scott Mcclay runs a W8 small block as does the Mozeris family.
