My best 1/4 time to date is a 13.0@109. This is with a slipping stock clutch and the stock all season BFG's, so my 60' was a horrible 2.2, Only performance mods were headers, cam, and tune....I havent been back to the track with it since everything else.
As far as dyno numbers, 478rwhp and 442 rwtq.
