Re: Chris Craft Challenger question – numbers?

[twostroke]

I had the good fortune to talk to Lee Holland Saturday 02/24 at an AOMCI meet in St. Clair Shores, MI about this numbering issue. He confirmed that the three or four digits preceding the J in the serial number IS month & year of production, and that the numbers started with 1000. He also confirmed that the oddball motor pictured above with a 4 digit number stamped into the head, and no boss cast on the cylinders is, in fact a very early production; the 347th motor built. He also added that this is the lowest/earliest number he’s seen.

I say "pardon me" a lot. I had a 20H, then raced open mod sleds.
