stock 1990 IROC-Z (350) specs/times?
This is the data that I read from an old Motortrend magazine... feel free to 'correct' it, if you believe it is inaccurate.

Horsepower - 245@4400
Torque - 345@3200
Redline - 5500
0-60 - 5.8
1/4 Mile - 14.4@97.8 (a few 14.2-14.3's)
Top Speed - 145 estimated (149)
60-0 - 132
Skidpad - .90 (a few .92's)

I was curious about the stock 1/8 Mile and 60-foot times? Also, does anyone have any idea what the 60-0 time would be if the 1LE brake upgrade was done?

-Thanks

I have that issue. They also state that was one of the quickest 0-30 times of any car they EVER tested - 2.2 seconds. 60' should be quicker than that. At least a 2.0
