As Rich posted, "Ask away!"
A 1956 235 car engine is considered to be a
"stove bolt six" engine (probably considered to be a "third-generation" stovebolt, depending on how you define the stovebolt-engine genealogy).
Stovebolt.com is this gigantic discussion board, and as described above it is dedicated to pre-1973 trucks (any GM truck, but mostly Chevrolet trucks).
Many car 235s engines are used as replacement engines in pre-1963 GM trucks. Your 1956 car 235 would have hydraulic lifters, a slightly different carburetor (probably), and a non-metallic composition camshaft timing gear. A truck would have mechanical/solid lifters, maybe a different carburetor, and a metal cam gear. There are also other differences between car/truck 235s.
Any of your engine question should be posted in the engine forum. However, be sure to state the engine is in a car. You might get a few jibes, but you will get better replies if car/truck makes a difference.
Any other car-only related questions should be posted in the Greasy Spoon, as suggested/posted above by Martin.
