I went 13.8 on street tires with just exhaust.

 

A 99+ GT can give a stock LT1 a good run if not beat the LT1 anyday of the week.

This guy comes and asks a question and all I am reading for the most part is bs, excuses and estimates.

 

dont waste your time with the LT1

just go LS1 if your serious

 

This is true. I'd say if you had a 99+GT/Bullitt 5 speed and a 93-97 LT1 6 speed, both with good drivers they'd be pretty even. The stangs put out an honest 260/265 hp and are 200 or 300 lbs lighter than the F bods. Both should net 13.80s to 14.0 at 100 to 102 mph stock. Auto vs Auto LT1 wins easily over the Ford simply because the 700R4 is a GREAT transmission from the factory. Ford auto's tend to have more parasitic drive train loss.

Trey if you're talking factory power, the LS1 is definately faster but you're gonna pay more money for one as well. The LS1 is a better motor though.

 

Not flaming your car either since your asking for a friend...lol...like group therapy..."I have this friend you see"....no but seriuosly a modded LT1 (just boltons) way out performs even the new supposedly faster GT's. I'm down to 13.2 1/4 ET with JetHot LT's, Moroso CAI, open Borla & Nitto 555s, all the free mod bs. She gets gears and a cam this weekend and I'm hoping to crack into the high 12's. I raced a 2003 GT with the new heads and new tranny setup and stomped the poor lil boogar 4 lengths. Stopped after the race and talked with the fellow and he couldn't believe I was a stock LT1. Funny thing is when my car was bone stock and running 14.00 1/4 ET I still outran GT's, go figure ...

 

I was going low 14's at around 97mph stock. I was running poor gas and didn't have the tires inflated properly but still they should run low 14's to high 13's. 99+ Stang would be a nice run and could take an LT1 Z just as easy as the Z could take the Stang. It would be a driver's race between the 2.

 

Revtime I'd be leary about telling people you'll beat the crap out of a cobra. Bone stock if the guy can drive they'll run 13.6s to 13.8's at 103 or 104 mph. You put in some gears free up the exhaust a bit and holy crap those things are bad ***.

 

Well now that's a loaded statement. I agree better in respect to more power stock, but truth is they do have problems, case in point, you cannot run a quart low on oil racing an LS1 without throwing a main bearing, very common problem vs an LT1 which can handle it, a few other engine issues with them related to power adders and engine longevity compared to the LT1. Of course there are opinions and I'm basing mine on what I've researched on various sites. The LT1 is a great motor to buildup, it's a beast, the OPTI issues are easy enough to overcome. Personally I think the LS1 will be replaced by a more refined version, maybe the LS6 but they have even better plans in the works.

 

Mustang guy:

Don't race him. He will beat you.

(that is all)

 

The times in the signiture are from the local track. I think they are low compared to what others have done, but HERE the average LT1 on street tires runs in the 14.3~14.6 range and the average LS1 on street tires runs in the low 14~high 13 range stock at the track here.

So I think the track is slow for guys with street tires.

BTW: Don't get mad if there is a bit of Mustang "bashing". I think that they are both great cars and the Stang has a bad *** after market, and alot of great options we aren't offered, like easy engine swaps, etc. I respect the Stang and they are defiantly nice cars.

I always thought a 94~95 GT with a mean 351 would be "FUN"!

Later, and stay safe

 

Where did you get this from? doesn't the LS1 actually have 1 quart extra capacity?

the LS1 may be more likely to burn a quart of oil, but hey, oil is cheap

 

Because of weather, location, environmental variables, vehicle condition, driving abilities, all you can reasonably obtain are estimates from which to compare. My earlier posted performance was from DelMar Delaware at the NHRA Division 1 Bracket Finals in 1998. It was the first time I had the car on a full 1/4 mile track.

 

hell in the 1/8 I could get most close-to-stock 5.0s in auto or stick trim with my 4.3L V-6 2 door blazer with a days worth of mods done like muffler, no cat, coil,intake, plugs, wires, thermostat and chip. I pissed a few of them off once I popped the hood. Mainly it was all out the hole cutting 1.8 short times with the slips to prove it. I even took a few all the way to the end in the 1/4. it ran a 15.7 at 89 in that trim and then I added 3.73 gears, shift improver, MSD 6A, headers, and other stuff.

When i had it the 4.6s were just coming out and they could just hang it up unless it was spraying

 

Mine ran 14.2@97 with stock 2.73 gears.

 

Ok you're right I should have clarified. For a normal daily driven car and for people who do check their oil the LS1 is a better motor. It's smoother, has more power and gets better mileage. It's also easier to a lot of the work on them as well.
