The easiest and trickest way I have ever seen anyone "remove" the A/C is this:
I saw a guy who used the standard A/C evaporator box and cut it parallel to the firewall about 4" away (about equal to the releif where the heater fittings come out). Then, he fabricated a pannel to fill the hole, mounting a set of gauges (water temp, oil pressure, vacuum, tac, etc.). It also gave him a nice spot to mount an aftermarket ignition box. All of your diag. gauges are right there in the engine comp. while you are tuning! I thought it was very tasteful. It sure beats modifying the firewall! And you can use the original A/C heater core. It does the job by getting most of the bulk out of the way.
Now, I would never condone chopping a BB evaporator box (although they make them repro now), but small block boxes are a dime a dozen, and you could use an already damaged one.
Now for the important question: do you have the original A/C hoses? If you do, and they are in good working shape, I would like to purchase them. Let me know.
