Caddy flathead info needed, please.

Hey, well i just got 2 346 caddy motors. The one that I have right now is millitary greenish, along with the 3 speed trans. I was just wondering what color these motors were when they came from cadillac and where to look for the numbers to figure out what year it is. I think the car I pulled it from was a 1941, but i'm not too sure.
Thanks, Dub...

 

They were an olive green, is the way I would decribe them.

Number is on the back of the block, drivers side, on a machined flat spot near the dizzy.

 

Thanks!

 

I don't know much about them, but I came across this car and an extra engine they had in the garage. Its a '40 LaSalle

 

I hear the counterweights are bolted to the crank!!! crazy.

 

I think it will make a good motor for my roadster... Thanks for the info guys!

Not so crazy. Intriguing, yes. (did the weights have a +/- factor?)
Manufacturing concepts are certainly progressive...
