www.firehawk.com has a breakdown of the numbers, and this site:
http://www.f-body.org/faq/faq.htm has a breakdown as well.

Maybe with a new Firehawk, but... perusing the June '98 MT, I am looking
at a 5.1 0-60 time and a 13.4 1/4mi time for a '98 Trans-Am. Since the
T/A and Z28 are identical with respect to drivetrain, you can extrapolate
the same numbers for a Z28. The Firehawk is a formidable car, but you
can't discount the new LS1. Feb. 1999 Hot Rod has a dyno test of the
LS1. Baseline for a stock '98 T/A was 296.00 RWHP and 319.5 lb-ft (rear
wheel). If you add a conservative 10% to that figure (for drivetrain
losses), you're looking at 325.6 flywheel hp and 351.45 flywheel torque
(factory specs are 305hp and 335 lb-ft). Again, underrated by the powers
that be. Only mag test that I could find that was faster 0-60 and almost
as fast 1/4mi time was the MCR test. The MT tests have a slower 0-60 and
a much slower 1/4mi time. Couldn't find anything on '93 or '95
Firehawks, but I'm not going to go through all of my car mags.
