ARE YOU SERIOUS DUDE!? Put the crack pipe down!!

I think those a-body 383s were rated at 300 (or was it 290?) compared to 325-335 for a normal 383. So yeah, they weren't the best, and all the magazines said so, and a bunch got replaced by headers. So for each set in the trash can, the remaining become more valuable. That said, that add is nuts, at least four times too high.
