Hmm...my car today has terrible 60' time, best being 1.87s...but that is because it is not setup for 1/4 mile racing at all. Instead the suspension is pretty stiff, HD leaf springs, sway bars, etc all in an attempt to make it stick to the road, lol, as much as an amateur build 3600 lbs vehicle can.

I'm curious though, so what were the before & after 60' times like?

In your case you were focused on max performance, and knowing the difference a move from 107 to 112 LSA had is pretty good stuff! Was the LSA the only change?
