    ok so I have a 94Z that I just bought for 800 put a used motor in (110k miles) I know it’s a good runner as it came out of my convertible 94Z. The previous owner had the A4 tranny built w/shift kit, The rear end built and a 3.73 gear.
    I will install a K/N CAI ($50 have), shorty headers ($100 have), 3”y pipe, cat back, and a custom mail tune. Was debating 1:6 RR and springs. What do you guys think this combo will run. Btw the track I race at is 3500 ft.

    2.0 60 foot with street tires. 14.0 @ 99.75 MPH My guess. With the 1.5 rockers.

    I think it will run high 14's with that elevation. One thing to make sure is to get the fuel cut off raised to 6500rpm as all LT1 engines have it set from the factory at 5800rpm. I had a 94 Z/28 and it was a fun car to beat on (6 speed) but after I raised the the fuel cut off added a open cut out at the rear and put 4.10 gears in it the car would hang with a LS auto car that has the 2.73 rear gear.

    With a stock engine, I would also say 14s, high 13s in top condition and sticking to the track.

    Thanks to all of you for your replies. I should consider some drag radials. I have trouble getting my 86 c10 to hook up at the track. Once again thank you guys.

    Some of the guys at Abel Racing where I dyno my car use the Nitto 555R tires.
    They are very good at hooking up.
    They gave me a worn set 275-60-15 that had went 9.0 in a mustang with LS power.
    They hooked up very well on the back of my 1957 4Door chevy.
    1.7 60 foot times with Spool and 4.56 gear with 4500 stall Coan.
    And my rim width was not optimal 5.5" wide.. Yes 5.5" and I ran 28 psi in them to go to the track and same to race.
    I think they are less expensive than some other drag radials.
    If you have not seen the launch here it is. Racing my old school 350" with 280H cam and 1.84-1.50 valves in 305 HO heads against a 2015 supercharged Mustang 5.0.

    Matters how well you can drive your vehicle.
    The mustang I raced in the above video cut a 2.1 60 foot time
    The 4000 lb long bed chevy truck of my friend with 235-75-15 mud and snow tires sporting a 6.0 LS that is tweaked and ran 13.5 also cut a 2.1 60 foot time.
    My old 78 Nova which I had 100,000+ seat miles in it I ran Uniroyal Tiger Paws 275-60-15 and I could cut 1.8 60 foot times with it.
    Track conditons driver skill how much low end TQ the engine makes will all be determining factors.
    Driver skill being #1.

    I have extra sets of rims for my vehicles and usually can score used drag tires pretty reasonable or just some other size tire.
    Stick the drag tires on when the need arises.

    Make sure you put a Yank or or a PTC converter in that 94Z, those seem to work well in the 4L60E trans. Last fall in our muscle car race I put a hurt on some guy that had a C5 Corvette, even though he had 119mph I put a 60ft. on him 1.56 that he could not recover from. My PP truck 461 easily handled that vette, he cam over to look at the car and shook his head after I told him what the engine was. For me torque gets the job done.
