That's pretty quick, especially on that slow a 60ft time. With all the mods you've done, plus the tires I'm sure you'll be in the 12's. Get that 60 ft time down and you'll see great improvements in time.

Mr Mojo

That's about right for the northeast. Your MPH is higher than mine was. I ran a 13.37@102 with the 2.59 gears and a 1.95 60'.

Those are some good times!When I had my 95 AUTO and did everything perfect,I ran low to mid 12's @ 110-112 in the 1/4 mile.Of course,the vortech supercharger helped a little. I think MR.MOJO'S time + MPH are about right for bone stock.

Anyone have a web or stats what stock C4s should run 84 to 97.

Mr Mojo

We used to have one here, but it won't help as times and mph will vary with location and weather.

Do a search on drag times, there are a few sites out there.

I have a 94 LT1, but with a manual transmission. I've only been out racing twice so far, and my best time (with drag radials, everything else completely stock) is 13.69, with a 2.0 60' and ~100 mph finish time.

I just need to be more comfortable with my launch, and winding out to 5999 RPMs on my shifts

So you're running pretty good times, in my opinion. A friend of mine who has a similar car (mostly stock) said he can run 13.1 - 13.2, that's what I'm shooting for.

for the other place that can calculate stuff.Scroll down when you get to the site and click into the correct section.
good luck.

If you listen to what many guys here are reporting, it's about average.

"free mods,3.73 gears ,full msd tune up,pulleys,aeromotive fpr?"

Free mods: nothing (you get what you pay for, sometimes you don't even get that.....)
tune: zero to not much (it doesn't sound like your car is out of tune now)
pulleys: half a tenth max
fpr: zero
gears: biggest bang; between one and two tenths with the auto

Don't count on 12's with stock LT1 power, even at your fast track.

That's my opinon, others will vary.

Are you still running your 36???, if so it's not going to last too long with slicks.

My 93 Ruby pig ran 13.8 @ 99.8 and I have the 3.07 gear. 60ft. time was 1.97 on all three runs.

Impala Balko

My best was a 13.7 @ 103mph with a best of 2.1 60'. I spin like a champ off the line... damn street tires
with Fidanza alum FW and K&N filter with cut lid and descreened MAF. with a 2000 RPM launch.

My best quarter time with a bone stock 92 LT1 auto, 2.59 gears, was 13.84 at 104 mph. Street tires were holding up my 60' times to about 2.1 sec. Just changing to 3.54 gears brought my best to 13.19 at 105 mph, although that was also on a track with traction compound at the line.

Thats pretty darn close to my best times at Beach Bend in KY. with a A4 & 3.07's
