The Stovebolt Site Forums The Shop Area General Truck Talk What engine do i have ?

Hello bolters ,

Just bought me a (bad) cab , engine with gearbox out of a 1956 gmc pickup I guess.

Since the l6 engine seems in good condition (good compression , no leaks to the coolant ) I would like to change most of the gaskets since some oil leaks are apparent.

I ve been reading and searching a lot on this forums and on the internet too, but i m una le to identify this engine?

The only stamped nr i found is behind the distributor C174099

Behind the starter motor is the casting nr 3837004 GM M
(This last M is further to the right of the engine , between distributor and vent tube
This M is casted in a square surround)

Behind the inlet/outlet we found a kind of "label" o E30 6 o
1 or I (??? About 4 " lower )
N (inclined about 45 degrees)

The cilinderhead outside the cover mentions 3836848
GM

Inside the cover between 1 and 2 cilinder 1

Inside the cover midst of the 5 cilinder D (inclined)

Outside the cover between 4 and 5 cilinder soms kind of "label " F o 7 o 6 o
(Where the "o" stands for a kind of what looks like a cast "head of a small screw"

Sofar what concernw the engine

Inside the cab , on tfhe left door pillar we found a tag aw follows

GM OF CANADA LIMITED
Made in GM CANADA
MODEL 1314
SERIAL 61314607513
ENGINE C174099
BODY SERIES 2819 TRIM
PAINT 5207

So it seems the cab and the engine belong together since the engine nr is the same

As mentioned above , my interest goes only to the engine , since i am restoring a 1959
which had a much younger v8 engine unted the hood which replaced the original l6
Somwhere oved time.
So I intend to re-swap it !

Hope sombody can help me with this issue, so that I could order the right gasket set for it !

Thanks anyway !

In the USA

3837004 was a 1956 235 block
It was the first year of the “848” head, which was used through the end of production of the 235

Hy Staf, welcome, by the numbers it appears your engine is a 1956 Chevrolet 235, hope that helps.

Hello Tim and Master Gabster

Thanks for the info
I will order a 235 gasket set than !

Staf,

Make sure it is for a high pressure 235 (most gasket manufacturers would call it 1954-1962 235).
The earlier low-pressure 235 engines used different gaskets (used also on the 216s, I think).

Welcome to Stovebolt, what are the plans for you new '56?

Welcome to the forum.

I want to add that the Canadian built GMC trucks were manufactured with Chevrolet drive trains so don't confuse the USA made kissing cousin GMC trucks.

Vintage Vehicle Services can report production numbers, color and other specific details about your Canadain built truck if you provide them your VIN.

Not that it applies here, but just to be clear 1954 engines used the same gasket as the earlier engines.

The pan gasket for a 56 should fit 1955-62 235, and 1955-63 261.

Welcome Staf. The M with a square around it means that it was cast at McKinnon Industries in St. Catharines Ontario. GM owned that engine plant for many years.
