Turns out I crossed #6 and #8 plug wires. It runs really well now. As for the loud hissing sound, turns out it's the LT1 alternator touching the plenum and causing a vibration. I will have to lift the plenum and clearance the alternator a bit with the grinder. As soon as I get my stock alternator rebuilt it goes back in.

Thanks to everyone for the help.
