I can't remember what year GM switched from points style distributors to HEI's, but if your car still has points, swap in an HEI distributor. Any truck wrecking yard will have one, as the 250 was in a million pick ups. Do that before you put a 6AL in it, it will make a big difference. Also, consider putting in a partial grill block sort of filler piece in underneath the "grill" in front of your windshield, where the wipers are. I think that was still there in '74. You need some airflow through it to feed the heater, but you don't need all of it. Pull your carpets out and take out all the insulation under them, there is probably 20 or 30 pounds worth of it in that car. Oh, and a chin spoiler under the front bumper, you can make one out pf plexiglass, those cars never had anything like that. Just my .02.
