sounds like a fun project.... i wish california had more relaxed smog laws.... if we tried that kind of stuff with a 1974+ car we'd be seeing the insides of a jail cell.... with gas prices at the rate they're at you'll make even H2 owners laugh ...
sounds like a fun project tho.... i'd reccomend stock heads with a port and polish... on the intake the victor jr might suit you better than the air gap... air gaps aren't the best when it comes to supercharging...... you might have to pick your carb depending on which supercharger you use as well.... i know if you wanted to keep it retro style, you would need to use a paxton, which gives you 2 choices on carbs, a holley 700 and a holley 750...
