Miami, For the small hp loss I don't know if it's worth the trouble to redo the engine. Typical loss is maybe 15hp. If you have room under the hood a different intake would increase the hp by a small amount. The addition of roller rockers would free up some hp also. Other than that you could change to aluminum heads. When we change to aluminum and move up to the next cam level we gain about 50hp. The next step would be a stroker kit. The cars I have had with air don't seem to effect performance that much. When in doubt I shut it off for the short race or display.

For the A/C I use the Vintage air mini space saver unit. It's heat/air/defrost in a very small package. I use the Sanden 505 small compressor. I don't know of an engine bracket that will work so I have to make each one to fit the car. Hood clearance is the main factor. The unit comes with small under dash outlets that work well.
