Good evening, just bought a 81 Stepside with what the previous owner said was a Commando 273, joined because I gotta figure this truck out and have some fun! What do I look for to see if this in fact a 273 or a 318?
Side of the block just a bit under where the block and heads meet on a 318.
Not sure on a 273.
