wow, you're right Tom, ITS weight is 2350. I forgot about that. 2550 is heavy! I'm just under 2300 when I roll the scales. I personally need to lose 10 or so pounds, but at 6'3, it's a long road to 180. I haven't weighed that since freshman year in high school. My car is an 84, and I still have the sunroof, and a solid front sway bar. The new hollow bar is on the workbench, and the roof is getting surgery this week, so I should be close to minimum.

I think the 13Bs do carry a bit more weight in the engine area, and the brakes are slightly larger, but I can't imagine how it could be 200 over.

That engine seems to have a lot of scoot from what I saw at the IT-Fest at Mid Ohio last year. He wasn't getting passed on the straight, that's for sure. (Standard disclaimer: it was just one example, with unknown mods, driver, and corner exit speed, YMMV )
