Re: So finally GM acknowledges the LT5 as one of theirs.
The LT5 engine cost as much as the car when ordering but was well worth the money as it made the ZR-1 special at the time. Love the sound as it whines out and still enjoy driving it today.

Re: So finally GM acknowledges the LT5 as one of theirs.
I really love the sound of the motor as it winds out. It has a turbine like whine to it.

After this went on a while, I finally gave in. We lined up on a straight country blacktop, free of traffic and driveways and he hit it from a rolling start. We accelerated smartly - turbine smooth - up to 5000 rpm and then he shifted into second!? I watched as he ran through second, again only as far as 5k (there abouts), and he shifted again. Third gear up to around 4k before letting off. "That's pretty good!" he says. But, I gave him pause cuz I was apparently rolling my eyes and shaking my head. He asked what was wrong, so I told him that he short shifted, even before the torque peaked. He says he was going by the sound, and it sounded like it was winding out "pretty good." Uh, huh... Well, we switched drivers and shot that stretch of blacktop again. Only this time I kept the hammer down to the shift light (7100 rpm) in the first 3 gears! Mind you he is an ex-cop, but the wide eyes and slack jawed expression said it all! (AND, I didn't have to hear about that Mustang anymore after that!)

Re: So finally GM acknowledges the LT5 as one of theirs.
Paul Workman! you are one mean shifter, (lol) I bet his jaws did drop shifting at 7.000 RPMs in all 3 gears. In all the time I have had the Z, have to admit I have never tried it. Perhaps I shall someday. Cheers!

It makes over 430 rwhp and still retains the stock cams and TB (508ish at the crank) - further testimony to what GM left on the table when the LT5 program was halted prematurely. Purrs like a stocker w/o a hint of what lies under the hood! https://www.youtube.com/watch?v=y1YFa8ruh8A Dave McLellan once said the LT5 should be run up to 7000 often, and the motor will thank you for it! And, of course NO example of what the LT5 potential is would be complete w/o Pete Polatsidis' incredible NA, stock-bottom ZR-1... https://www.youtube.com/watch?v=SFNFOhGGlR4

Re: So finally GM acknowledges the LT5 as one of theirs.
Just a note on how "ownership" of the engine was viewed. GM is (especially at that time) a huge company. Each of the respective organizations had their own culture in some ways. Certainly GM Corporate and the Chevrolet organization as a whole felt ownership of the LT5 and the Corvette as a whole. The NIH syndrome would only really apply to GM POWERTRAIN as their involvement was more limited. Even more so, the Powertrain organization is typically divided into different groups - Powertrain planning, Base Engine design, Engine-as-installed design, calibration, & manufacturing. Only the base engine design and manufacturing departments would not have been involved directly (though they had an oversight role).
