Need brake advice

[dawsonthompson]

Ok so I'm redoing the brakes in my 66 which has the current stock single reservoir master cylinder. I know i need to upgrade to something beefier since i have the bbc in it now. However cant decide what will be more efficient either upgrading to a dual reservoir with or without a break booster, keeping my single and just adding break booster, or swapping to front disc and leave the rear drums or change them to disc too. I do know the price differences between disc and power and i am willing to save for if needed, just don't want to spend the money if upgrading to a better manual setup will do just fine.

Thanks Dawson
