Not from the factory, I've seen one 3rd gen LT5 swap, I think for the 91 SEMA show if I remember right. Those engines are few and far between, they were hand built here in Tulsa at Mercury Marine, and the later version (93-95?) was a quad cam monster...405 rated hp I think...good luck finding one without tearing apart a rare and expensive C4 ZR1 Vette....

I'm saying even steven here. my buddy had a lt4 vette and sat right next to a ls1 at the track in 3 races and yes he does know how to drive. I also heard the lt4 was also under rated,possibly actually around 375. Just what I heard. My buddy ran 13.10 / 109 mph on a 95 degree chicago day. with only mufflers, not even a cat back.

Well I saw a stock C4 GS run a 12.8 or 9 back in '00, so I think it'd be a driver's race, and I'd probably give the edge to the LT4, esp. if it's in a C4, which IIRC is lighter than an F-Body.
I remember there was a few LT4 SS's running around in '97, I read about them in Super Chevy back when they were new. I think SLP made a few of them.

NO, IT'S NOT......, his car was a 96 collector 6 spd lt4, almost same car as the GS that was mentioned, claimed to be under rated also! Not arguing just saying , but then again we all have heard different stories.

All manual trans 1996 C4 Vettes are LT4's amd 100 LT4's were installed in Hardtop 30th Anni. SS's in 1997 again 6spd only.
Out of all the street runs I've done in my LS1 I never had the pleasure of running an LT4 car. But I agree on it being a Drivers race.Craig

I owned a 1996 C4 with the LT4. Excellent engine.
I was able to run very low 13's with the car bone stock. My guess is the LT4 C 4 would be faster in the 1/4 mile than an LS1 F-body. The best I've ever done with one of my 3 stock F-Bodys was 13.5.
I'd be willing to bet that the 97 F-Body with the LT4 would be a drivers race versus a LS1 car.

I wouldn't mind finding one of those lt4 firehawks. Loved the look of my 96 ws6 formy. I should have kept that one. my very first new car.
