I know they built at least 1 such engine: it was in my car until 2008. Did they build more? How many? I’m curious to know those answers!

I’m also interested in acquiring another, currently working on not. Refreshed, old, running or, a long block that still turns or, at the very least, complete, correct pieces (case, P&Cs, heads, etc). Induction is less important (mine started with Webers and finished with MFI). Bonus points if you have/find serial number 6121036.

I’ve asked about 6121036 periodically the past 20 years. This is my final query.

Thanks!
