I didn't say 80's,,,,I said towards the end of the 3rd gen production,,,SLP was most certainly involved with 3rd gens,,,,and made a few Firehawks and such with various options,,,,,like removing the tune port setup in favor of a mini ram type setup,,,,also one of those being the 6 speed trans we were talking about.

I am with Mrr23 on this one. I have never seen nor heard of a 5 speed in an LT1. And I have seen a ton of these things.
GM wouldn't put the 5 speed behind the 350 tuned port injected cars,,,so I especially don't see it happening behind an LT1,,,an engine with higher HP and torque ratings at that.
I am pretty sure I have an article around, where Hot Rod or some other mag road tested one of the first new 93 Z28's hot off the assembly line. It was a 6 speed model I remember clearly because they did alot of praising about how you could finally get a 350 in an Fbody with a manual trans and talked about it being the same 6 speed in the vettes.
If there were in fact a few factory equipped 5 speeds in an LT1 I would have to see one to believe it. I sure don't remember any literature on it.
With the power of the internet I would think we could look that up somehow?

Well there ya go,,,,here they have a pair of TPI 350 cars, and the bone stocker they put a thermostat in it and bumped up the timing a couple degrees and it ran 14.20's.
The SLP version with headers, cat back, and intake runners ran 14.0's at 100 mph. It certainly has easy 13 second potential.
Mine with just headers and cat back ran 13.90's at 99 mph. Right on the money with these other cars. My car wasn't a freak, it ran typical of these cars back then with a few tweaks.

tpi 350s are no joke, tons of low end power.

I see all the pissing about SLP, what motors, etc. - but not one person has questioned why they want to do a gay roll race.
Run from a dig, the end.

No such thing as a production 5 Speed LT1 4th Gen. Surely you can easily put a Tremec TKO/3550/500/600 in an LT1 4th Gen, but they didn't come that way from the factory. The only 5 Speed readily available back then was the Borg Warner T5, such as those found in 5.0 Mustangs. They simply weren't rated for the torque of the LT1 (or the L98, for that matter).
There were some L98 3rd Gens that ran low 14s. It wasn't the most common thing in the world, but it did happen. I also laid eyeballs on a 91 Z28 at Great Lakes Dragaway back in the fall of 90 that was running very consistent 14.2s, bone stock. The guy was cooling the motor and icing the intake...but that didn't make it any less stock.
That said, the majority of 3rd Gens (and even the majority of L98s) didn't run that good. Most of the 305 cars were high 14 to low 15 second rides.
FYI, we had an 85 Z28 (305 TPI A4) that ran high 9's in the 1/8th, stock (this was in the summer of 1988). It certainly didn't set the world on fire, but it sure was a sharp car.
