| | | | Joined: Nov 2014 Posts: 15 New Guy | | New Guy Joined: Nov 2014 Posts: 15 | I have a 1951 3800 with the following information:
Engine Casting Number - 3835911
Head Casting Number - 3836848
Engine Serial Number - HCA408364
I have researched and found that the engine is a 235. Is this correct?
I can't find the Serial Number anywhere. I can't find the head and engine casting numbers together based on the research and sites I have reviewed.
Any help on figuring out what I have?
Thanks,

3836848 is 235 also but usually from later years. it may have been a replacement head. Good possibility you have a early conversion from a 216 to a 235 | | | | | Joined: Sep 2001 Posts: 29,269 Bubba - Curmudgeon | | Bubba - Curmudgeon Joined: Sep 2001 Posts: 29,269 | 3836848 was used from 1956 onwards HCA408364 HCA was the Engine Serial Number used on 1950 4400 series truck - 216 engineAHCA was used on 1950 3800 216 engines As posted above by thoroco (Dave), this is not the truck's original engine.

Date code for block - CON3 B225
I can't get to the head date without taking cover off, correct? If so, I will have to get that date at a later time. | | | | | Joined: Nov 2014 Posts: 15 New Guy | | New Guy Joined: Nov 2014 Posts: 15 | I do have a Bowen Machine emblem attached to the engine with the following info:

B225
B = February
22 = 22nd
5 = 1955
That block casting code, 3835911, was used from 1953-1955 on high-pressure 235s used on trucks (up through first series 55) and 53-55 Corvettes. It should have mechanical lifters and it should have the higher-mounted, earlier water pump (in the correct location for 1951 radiator). The fan belt is most likely 3/8" wide.
