Locating the Numbers

Many people want to get a replacement engine.  We determine a match by the Casting number, only.
Engines may have been swapped, changed, and replaced over the years, what you think should be in the car/truck, may not always be the case.

Using the Casting Number is the best way to determine if we have a match.

This Labled photo gives you the details.
Note: The Date Code is based on the Casting number.
Since this is a 1937-38 block, we know the “8”, means 1938.

Only a few photos of the engine components on this build.  Guess I was MIA with the camera.

Specifications for 1937 and 1938 for passenger cars and trucks

Cool data from the GM Vehicle Information Kits for these years.
For those who need to know, I’ve got pages from the GM Heritage Archive, the Engine Sections, for 1937/38 for Passenger Car and Trucks.  The data may be the same in each, but I figured putting up all 4 was good.
