FactoryStock,

Along the subject of "327 engines in 1964 C 20s and 30s" do you know if the Oakland plant was making big trucks, e.g. C50/60, in May of 64'. I ask because, have a 64' C20 with a 327, suffix is correct for HD truck UG and dated mid May 64.
It is a totally loaded truck from CA desert, has three gas tanks.

Question thinking about, where did the special order 337s in 64' come from, e.g. Supply line for big truck line at that plant, or did flint specially make these 327s for each, or some plants, to be use in C20/30s.

Still confirming that mine is original 327 install, looks like it.
O Oakland mid May 1964, engine suffix pad. The VIN is around 170,000.

Thanks,
Les
