something is wrong!?

I for one, think you should 60 ft. better than that, with that much power. 60 ft. is where the E.T. comes from.

Myself, I would throw more gear at it.

Of course, you are talking to a guy that use to run a 5:38 gear with a big block, and 60 foot times were around 1:37 to 1:39.

With that short of tire, I would at least go 4:56 on the gear.
