Default Engine Dyno info from Mercruiser

What if any info has anyone received from the museum regarding the dyno sheets for our cars? I know this has been beat to death here, but I have a opportunity to chat with Jim Campbell from Chevrolet today and was curious if there have been any developments regarding the owners getting the dyno info for their cars?

never going to happen. we've been trying to get them released for years and GM won't let it happen. Best advice is to forget they exist

Ok, I'll bite. So, what's the big secret?

When our motors were finished with the assembly work they were tested in a test cell at the Merc plant. If they passed muster they were packaged up and shipped to the BG plant to wait to be put in our cars.

The data sheet from each engine was printed out and attached to that specific motor's documentation from the assembly process. There are dyno sheets for each LT5 Merc built and GM stored them at the NCM with the rest of all the corvette documentation that the NCM stores and preserves for GM. The kink in the works is that GM gave specific instructions to the NCM that the LT5 dyno sheets, (and I assume the Q/C reports for each LT5), are not for public consumption like the build and window stickers that they let us vette owners get copies of.

Holy crap. I had no idea. Now I wish I didn't know they existed.

Yea, it's kind of like the hospital where you're born having your birth certificate and telling you you can't have it after your 18th b-day! LOL

I just wonder if it is an actual graph or is it more a spread sheet of power vs rpm? Either way I'd like to add it to my car's pizza box just for the sake of "having all my car's documents". I'm wondering what other assembly documentation may have been preserved. I know there were great pains taken in the assembly process at different stages to check dimensional accuracy after major parts were done being machined. I'd even like to have that stuff, if it was saved. I know I'm rambling, sorry!

It's just if you think about it, we own one of the few American production cars ever assembled that came standard with a hand built motor! I mean that is a bit of a rarity, no? Oh, and I point that out to all my C6 ZO6 buddies just as a matter of distinction between a hand assembled motor vs a hand built motor.

I seem to recall that all this info was given to the NCM.
However, they may have been issued instructions about
how the information could be dealt with?
Anyone else remember anything on this?
