Well this weekend I ran a GM. I was going home from work through town and there were countless ricers. I had to laugh because I enacted a no-flyby-zone on a black jetta w/ a "badass" punk and three girls. After I left them like they were still, he pulled up to me and I saw three wide open mouthes. hahahahaha

As I am almost home, I spy some familiar headlights coming up and what do I see??? Non other than a Trans Am. From the body style, I can tell that it is the older LT1 version. We catch a light and the guy is in there w/ his GF. On green I just edge out and keep it in first and about 3500rpms. Then he hits it. He jumps to about a hood ahead and stays there. My bumper is at his door. From there we take off and by the middle to top of third, I run right by him. We then immediately had to stop for a light. I ask him about his car and he tells me it is, "an LT4 that is running bad." I know that they should run like an LS1 and I would have been destroyed. I then was able to on a future launch to spinn from a roll in first at about 4000rpms. He wouldnt even mess w/ me.

I will not claim a win because he very well could have stopped when I went by him. I just dont think it was really an LT4 or he had a really damaged car, or REALLY bad driver. What do you think???

There was an LT4, it was stock in the 96 Vette manual cars as well as the Gran Sport, as well as a very limited number of SS Camaros and Firehawks. The parts (heads, cam and intake) where also avalible from GM to convert your LT1 to an LT4. They were generally 300+ hp to the wheels and should be about even with a stock LS1 performance wise.

yea, the LT1 to LT4 conversion seems like a popular upgrade for the LT1 guys around here. I just think that he was B*llsh*tting me about that mod. If he did have it, he should have walked me, esp. from the 5mph roll we did. I find it hard to believe that his car was "running badly" but running and he couldnt beat me. I actually have a hard time running w/ the LT1 camaros and firebirds regardless w/ their 275-285hp. idk but I smelled a rat.

The guy was lying, even if this story is true... Even a crappy running LT1 would destroy a '96 GT. An LT4 wouldn't bother.

Yeah, that would have to be a reeeeeally rough running LT4. Those made 330hp stock if I remember correctly. It's essentially an LT1 with a little higher compression and bigger lift/duration cam and some other things.

You're lucky it wasn't an LT5 :P

Like stated above the LT4 was an option in 96 which came in the Gran Sport Corvettes. They are identified by M6 tranny and will have the 2 big rally stripes down the center of the car. All other 96 vettes were autos. And yes, there were special edition Camaro and Firehawks that had the LT4 but never a GM produced car. Aftermarket companies such as SLP and others installed the LT4.

The LT4 itself was a good powerplant. But the conversion kits sold have a different cam known as the Hotcam. It's bigger than the stock LT4 cam and use a 1.6 roller rocker as opposed to the stock stamped steel 1.5 ratio rockers. The heads and intake differ due to a .100 taller intake runner. The LT4 intake can be easily identified due to it being red powdercoat. But that doesn't always mean it's an LT4 or not. Mine is powdercoated Purple and it's an LT1 intake. (wifes idea. her car)

My current Impala set up is a Hotcammed LT1 / P&P LT1 aluminum heads.

If the guy had a bad tune or no tune, his car will run like dogpoop. My car put down 250 w/o a tune then jumped to 322 with a mailorder tune. Due to I installed bigger injectors, etc to facilitate the heads/cam. So the whole tune was outta whack.

But, he coulda been blowin smoke trying to intimidate you.
Nevertheless, good kill.

You mean...LT1 Vettes were autos in '96. ALL of the M6 Vettes in '96 got the LT4.
