awesome car. I had an '86 that I went the 455(467) route. I was able to modify the factory brackets to make the a/c compressor,p/s, alternator, and yes, the airpump function. I even "drop based" the aircleaner so it could still fit under a stock hood with the intakes 2 inch raise. Ran high 12's, and everything worked. But then I sold it to buy a GN. If I ever attempted it again, I'd go built 403 with the edelbrock heads and mondello cam.
