Yeah, I've seen pics from under the engine bay and it was pretty clear there was far more happening chassis-wise than the exterior would lead you to believe. And I watched the episode about when he picked up the new engine and know it would snap my E-body in half w/ the spray "full on".

If I had to guess (and I'm pleading major ignorance here since all I know is what's shown on the tube, plus a few misc. other bits of info), I'd expect it could pull a low 8-sec pass in the 1/4. At some point the aerodynamics & weight (ASSuming it's still pretty freakin' heavy) got to put a limit on how fast it can go. I don't have a good 1/4-to-1/8th converter in my head, so I can't factor a 660 #.

EDIT: Just saw where you stated "The truck ran in the 5s on spray with a 502 crate motor BEFORE he put the big motor in it." so I really have NO clue how fast it is now.

EDIT #2: I'd still like to know how fast AZN's "Dung Beetle" really is, but it's fun to watch, regardless.
