Hello all, I'm brand new to the forum, and as of today also the new owner of a 43 Willys GPW. Being new I'm not 100% that I am posting in the correct area of the forum, so please scold me for any wrong doings. Now to my question. I'd like to find out some information on my engine tomorrow. It's a Buick 231. Where would my Numbers be stamped on this engine so I can figure out what it was pulled from to go into my willys? I'd also like to know if it is one of the oddfire v6's or if it is the evenfire..Anyone know distinguishing factors? Thank you all for whatever advice you can give me. It is all very much appreciated!
