The Stovebolt Site Forums The Shop Area Engine Shop Help needed to ID my new motor

Picked my motor yesterday and spent today trying to clean it up. Now I’d like to ID it to know what I have. It’s supposed to be a 235. I went to Deve’s website (devestechnet.com) looking for serial #’s but none there. I *was* able to learn that the head casting # indicates that it is a 1954-1955 235 head. Just don’t know about the block because there apparently isn’t a block casting number, or at least I can’t find one. Help with the serial # would really be appreciated. Pics attached. Thanks

Serial # OI95I95F55X (EYEs not ones)

Head casting # 3835913

Look for the cast #in front of the crankcase breather tube, between the pan flange & horizontal cast rib above it.

Head: Pass & Powerglide: 3835913 = 1954/1955 235

F55X 1955 3100 truck 235

The engine serial number 0195195F55X tells it all...

0195195 = unit number starting with 1001
F = Flint engine plant
55 = year (first series 1955)
X = regular 235 for a 3100 truck

The block casting number is on the passenger side near the front just above the oil pan.

Thanks BC, tclederman, and Mike B. Now I know what I have.

I believe only the ‘53—‘54 models had the high water pump, correct? ‘55 and newer would have to have them relocated to use in the ‘47—‘54 trucks, correct. If mine is a ‘55 and the water pump is high on it then it was relocated, correct?

" . . . ‘55 and newer would have to have them relocated to use in the ‘47—‘54 trucks, correct. . . "

I think that the 1955 First Series 3100 trucks had the water pump in the "correct" (earlier position).

Hopefully, someone will correct/confirm this?

A 1955 first series was basically a 1954 truck with open driveline.
It used the high mount water pump.
The 1955 second series truck was a completely redesigned truck, with the new lower, longer water pump.
In passenger cars the low mount water pump started at the beginning of 1955.
