1967 Chevelle

[BBIGG BLOCK 396]

I am going to look at a 67 Chevelle SS ,it is suppose to be a original 375 HP /396 car but also has factory A/C. Could you get a 375 HP with A/C!What would I especially look for to see if it is a real 375 HP Car.Guy said he does have some papers with the car but not sure what all he has.He was pretty vague,said he had not looked at them in a long time and just does not remember what all is there.Any help would be appreciated.

Thanks
