Tom: I have a 1974 GM rebuild manual enroute to me at this time that will cover the 250 engine. This manual assumes the engine is out of the vehicle already but I do not know yet if it assumes the engine was pulled with everything attached to the engine. If the manual has what you need we can figure out a way to get that info to you. I don't know when the manual will arrive ..... it is coming U.S.P.S. Ray
