Does air conditioning effects on different size motors?

Hi,

What would help a car not burn so much gas when running the air conditioning? In other words, if the gas consumption is awful with a 307 c.i.d. engine will it "NOT" be so bad with a 350 crate motor or a restored Cadillac 500 c.i.d. engine?

What are the variable specifics on whether or not an a/c compressor will take a considerable toll on a car fuel tank and mileage?

I just figure it was some kind science to the whole thing.


Please help.

Thanks!



I didn't find the right solution from the Internet.
