Jerry, In you stock of LT5s are the two dates real close? Whats typical?

This thread seems to keep dying, so I have to bring it to life.

Discussion on this has been very interesting, still waiting on thoughts on Eric's questions above & any one with a '90 ZR-1 numbering in the 2000's (or any '90 Z really) somewhere to compare the casting date on their LT5 with their build date. 70-something day lag seems like a long time.

I want to figure this mystery out!
