This is just my opinion to your Q. I drove one of those STSv's w/the blown N* and I thought for a fairly big car it was pretty good. I drove it for about 15 minutes so what can I say. I also never drove anything that was forced induction so what would I really know, right?

I guess money troubles could have been the cause of the LT5 and the N*'s death and lack of development? I'm thinking that the LT5 program from 86 was allowed to go forward to help not just corvette, but also to maybe show the way to the Olds & Caddy guys how to do a DOHC/4V motor? The Aurora & N*'s came after our LT5 was ready for production, right? I figure that the corvette guys broke the trail & smoothed the way for the Olds & Caddy guys? I mean why waste $$ on three development programs right?

I'd like to think that Lotus probably owns the rights to the design of that LT5, but maybe GM is waiting for the patent to expire or something. I hope they go back to the DOHC with the next gen vette. Didn't they shelve plans to build a new DOHC family of engines right when the economy tanked and they took all the money from the fed to stay in business? I bet we see that ramp back up again soon.

I would venture to say that G.M. owns EVERY aspect of the LT5.

Cool picture, A1990! I've never seen a picture of a gen II LT5. Wasn't even sure if any of those motors existed. Got anymore pics of it?

Check out issue 14, June 2008 of the Heart of the Beast. Lots of pictures and information on the engine. It was variable cam timing...

Re: Prototype Engines

Would make a good Yacht Anchor! Looks kinda heavy :cheers:

Well, I would but I don't have any of those. 2008 was before I had a ZR-1.

Thanks for posting up those pics, WB9MCW!

Re: Prototype Engines

Now that engine would be a lot easier to keep clean.
