What is the Engine Degree Angle on a 1954 Chevrolet 1/2 ton truck?
Out of all the manuals & catalogs that are available.
I cannot seem to find any data on the Engine Angle of a Advance Design engine.
Is there anyone out there that may know where that data can be found?

What angle are you looking for, measured from where to where?

The inline 6 has a 0* angle between cylinder bores, unlike the later V8's 😉

Engine Block angle or pitch from front to back.
The front of engine block is higher than the rear.
Or what is the angle or pitch from the front to back of the crank shaft.
The front of the engine is the end of the engine where the fan is mounted.
Or how much is the engine tilting down, from the front to the rear inside the frame?
Assuming the frame is level.

I carefully measured my 51 GMC 1 ton and I think all AD trucks would be very close if not the exact same.
If the rear part of the frame were level, the part under cab and bed, (not the front frame beside engine which slopes down.)
The engine is tiled back 3.5*

It seems that I've read somewhere that when the vehicle is sitting on level ground the carburetor should be level. Is that correct?

jfnar, Carbs are level because most intakes, at least V8, are cast with a thicker/higher cast at the back for this very reason.....
or so I think. I'm sure someone will correct me or explain it better.

Yes, I was just thinking that would be a good way to check that you have the engine at the correct angle. Just put a level on top of the carb or intake manifold. Just a thought.......

Most carbs work best when they're level but there is still some leeway and depending on how the truck is loaded or not it may or may not have the carb surface on the manifold dead level when the truck is on level ground.

I like the original question if you're trying to put it back together as originally designed then reference the angle between top of the block (or oil pan rail and/or similar parallel surfaces) to the straight part of the frame rail.

Is there enough play in the mounts to even make angle an option?

I ask out of ignorance. Always assumed this took care of itself.

All original it takes care of its self, but if installing a much different engine it is something to think about.

I don't know about the trucks but I believe the early 216s in the cars changed in angle as the design evolved and the intake manifold changed to make up the difference.
