Thanks for all the info, guys. The fellow who did my regrind suggested that I run a manual transmission with this grind, which was my plan from the start. I also will be converting the w/s wipers to electric. This leaves me with the brakes. I originally wanted to use power brakes. The brakes are 10.5 inch GM disks on the front (using '79 Malibu calipers) and 9.5 inch GM drums in the rear (I plan to upgrade to disks someday). I have a concern that I may not have enough vacuum for the brake booster and I do not want to run a back-up electric vacuum pump. Would it be better to run a dual diaphram booster or use manual brakes with a large bore m/c?
