Anyone know anything about flathead 6 engines?

Here is a site for mid 40s/early 50s mopars:http://www430.pair.com/p15d24/mopar_forum/

Tried to get on, but really ridiculous registration procedure. They ask a mopar question, and if you cant answer it, you cant register.

Couldnt answer the question, so cant register. Not worth the aggravation.
