Hey guys, I just picked me up an 80,000 mile 1992 Z-28 (L98)/700 R4. It is in excellent shape and feels real strong. Here are the mods: SLP runners, Accel 8.8 wires, cap and rotor. K&N filter mounted directly at TB. SLP 3" catback/muffler. Flowtec 3" cut-out. SLP shift kit. The tranny hits real hard and it gives all autos a good name LOL. I believe it has 2.73's out back but I'm not sure. I run the car at sea level here in FL. The best I got out of it was a 14.3 w. 2.1X 60'and that was on a cool and crisp night. Consistent 14.50's when it's hot outside tho. Where do you think I should be E/T wise? Do these times look normal or am I slow?

 

Your times look normal to me.

Yea, I could hit probably 14 flat on a cool day with some DRs or atleast ANY traction. Your car has 3.23s all the 350s had 3.23s from 90-92. Perfectly fine to me. Get that 60ft time down some and some 14 flats won't be out of the question. One in the 60 is worth 2 in the quarter. ALWAYS remember that
