It is all going to depend on how much boost you are going to run and what you hp goal is. If you can tell us what your hp (at the crank) goal is and what the car is going to be used for (street, track, etc.) that will help. You are going to be pushing the fuel pump, stock fuel pump hanger (the size of the connections), fuel lines, and the injector rails to their limits so you may want to look at a complete fuel system.

Vortech goes with pretty much everything:

I haven't seen that Harrop kit before, i guess the price is high, but pretty much all kits like that cost a ton these days, we were just used to $2000 vortech kits, so most superchargers seem expensive to people that have been around a while.
I'd be curious on how it fits under a hood, i always thought one of the issues wth screw type superchargers on pushrod 302s was that when you put the intercooler under the intake, it made the engine too tall.

Hell, you ain't 'kool' unless your supercharger sticks outta the hood all shaking, loud and scary.

Honey, I can't see the road!!!

Your list is impressive, but running electric fans with the 75 amp alternator not so good for your Holley electronics.
You'll likely be in the 6-700ft. lbs. Of trans shredding power and the tko will be tko'ed .

small typo on first post. actually now running a 125 amp alternater and yes i did have issues with the original electric fans not spinning at full power with the 75 amp alternator...car actually overheated and blew a head gasket...switched to the 125 amp and contour fans and overheating was solved.

I'm not a fan of electric fans on a blower car. In Texas my Procharged 93GT wouldn't stay cool with electricals. Stock type clutch fan. Now that was with a 3 core intercooler up front stealing airflow. Any your fuel system isn't enough, unless you run 5 lbs of boost. AND TRUST ME, THAT WILL HAPPEN FOR 5 MINUTES-MAYBE.
