Gasoline smell at WOT

Since swapping the ZZ502 for an LS3 I now get a periodic strong gas smell after getting on the throttle. Tank is in the rear (not the cab) and there are no leaks that I can locate.

I'm running all 4 eRod cats plus a factory transverse muffler, so I'd figure it would burn up any excess fuel, but I guess not.

Has anyone else noticed this? I think it almost has to be in the exhaust, but that's far behind me, dumping behind the rear bumper, and this is while underway of course.

Thoughts? It's not bothersome, really, but I worry about any gasoline fumes that I cannot explain.
