The Shelby parts book lists C5AE-9350-G as the pump for Shelby 427 Cobras. However, it doesn't list a manufacturer or a model number.
My 1967 Ford Master Parts catalog lists AC pumps 0294 and 6974 and Carter 4441 as "427" pumps of various years.
My Carter pump catalog lists AC model 4918 for the 427 engine.
My Master Parts catalog doesn't list a C5-9350-G pump.
So, what pump(s) actually came with the 427 powered Cobras as delivered?
