Advice on interpreting AIM regarding AC and Cooling Systems
I came across this last week at work and could use some insight here. I don't have enough judging guides here at home - just AIM's - to aid in research.
When looking in the RPO C60 sections of the factory AIM for 1969-72 on the non-illustrated parts page under "Radiator & Grille", it calls out for A/C cars to be equipped with the cooling system of the lowest HP Big Block for that given year (L36 for 1969, LS5 for 1970, etc). This appears to be a uniform callout - has A/C, install BB cooling. No mention whatsoever of deviating from this if the car is a SB. This isn't the first option code that calls for BB Cooling with the installation of an RPO. Example - the 1970 AIM in the M40 section calls for using LS5 radiator assemblies, yet I've seen SB cooling systems in SB/Automatic cars.
In looking at other customer cars, restoration guides, Dobbins Vette Vues Fact Book..... I see SB cooling systems using the wide Cooper/Brass radiator with a cap, venting to earth in SB with A/C.
I've attached page scans of the AIM's I have here in relation to the C60 RPO for your review. Based on how I'm interpreting the AIM, there were a lot of cars not built as called for.
So did the assembly line not RTM on (potentially) scads of cars, or is there a more definitive call out further in the AIM that I'm missing? What have you guys seen?
