Guys,
In about 3 weeks I'm FINALLY going to get my engine back. I have a few decisions to make in the next couple of weeks like:
1 Is the fuel line (3/8)large enough to deliver enough fuel?
2 Is the 750 cfm enough carb?
3 Anyone have a header recomendation?
4 Is my existing ignition sufficent?
I welcome ALL suggestions,this is the LAST time this engine is going to be put back in this car!!! (until the next time ;) )and I wanna get it right. Thanks here are the particulars:

1.) 3/8 should be fine as long as it's not 'kinky'

2.) I think you'll like the launch better with a 750, and the top end better with something bigger. But start with the 750. Carb swaps take 5 mintues.

3.) Not thrilled with my high dollar Hookers ( yea, I wish), Summits or Dynomaxs are perfect and fit a 70 very well.

4.) My Pertronix I spins to 7200+. Added an MSD for better fire 5000+ rpm. Seemed to help, also like the MSD6AL for the rev limiter. Too easy to lite 'em up and pass 7000 without it. Wouldn't want to push a hyd roller anywhere near that far.

Sounds like a well thought out combo.
