Here is the casting # on the motor Block
B166
(977)(8787)
XS on motor pad
Very rare car if an XS code block. Should have head code 093 on the center exhaust ports. This is a late production run beginning July 1966 know as first factory production Ram Air cars. Should have an open hood scoop and factory tri-power Ram Air tub that sits atop the carbs. Front carb number should be 7025178, center carb 7026075, rear carb 702 5179. Engine uses the Pontiac "744" cam. It is said that only 185-190 cars were built with the factory XS Ram Air engine.
