RTD,
Yes, 351E V6 is original to suburban, and it also has dealer installed AC from when new, I think. Date codes on it are December 1065. Will post some photos of it. They will be some older photos, all the engine external accessory parts are packed away right now. They are inventoried per container.
The other 351E V6 engine, from a 1966 C30 dump truck, has 4 speed with PTO. If I remember correctly it has the optional 4 speed transmission. It is locked up, trying to free cylinder two cylinders, soaking with rust penetrating oil no luck. It is low mileage, under 50K. To bad it must have got wet some how. Cylinders stuck are ones where exhaust valves were open. Lesson, if storing, losses rockers, storage oil in cylinders. It is very original little touched. Some good some bad, e.g. oil in it looked like partial sludge, maybe from moisture?

Will get back on PS.

Like the 351 magnum exhaust manifolds, they are big! Also, strange that the intake is a single plane design.
