A/C big cam?
 

Do anyone know about a AC kit I can pick up that does not have a lot of drag on a engine that has a big cam? please help I am in Texas lol I would like to have AC this summer but I have a big cam in my 406

Yes, ALL the aftermarket kits use a smaller , low drag style compressor like "sanden 508".

The days of big clunky , horsepower robbing compressors has been gone for a while. use the search function on this forum , there are many informative write ups about A/C.

Here is one of many links

Convert to an LS compressor.

Lot cheaper to just install a solenoid that kicks the throttle linkage up a little bit when then a/c kicks on. I did that with my 383, works good.
