I updated my vacuum brake booster with one from Tuff Stuff, on my truck. That made a serious amount of difference in operation with my 383 engine's vacuum. The booster responds better and does not seem to run out of vacuum as quick as the factory unit did. You may want to go into your 700 tranny with some updates to make it align with your cam and drivning style. I rebuilt mine to use the heavier clutches, planetary and sun housings. I don't have that slip issue now. I also did the valve body with heavier springs and a hardened seperator plate.
