The Stovebolt Site Forums The Shop Area Engine Shop How do I tell what 6 Cylinder I have

I'll hijack a thread. Have a '48 6100, with i believe a 235. Only numbers that I could find were B53 848 850 above and to the front of the distributor and 3836848 cast onto the head. I've looked at the post on here and at inliners and can't figure out what motor it is. hoping someone can chime in and answer.

thanks
