Formula 350's where good for about 14.4 not sure on the MPH, GTA and T/A ahould be in about 14.6 or so.

Here is a list of some performance data as tested by some popular magazines. IMHO they all seem pretty weak, but its as printed in the mag:

That's a good time for a car with 245? Hp. What gears came in the TPI 350s, 3.23's only or were 2.73's optional. I was wondering because I figured the TPI engines would 60 foot alot better than my LT1 with 2.59 gears. Without a burnout and rolling throught the waterbox (had to cause the track is retarded and wets the whole lane) I cut a 2.06 60 foot. Cut a 2.14 when I ran the 13.7 cause of the damn traction control, hehe.
