Guys with the GMPP carb intake... Figure more of you would be in here than the bolt-on section, what size hole did you drill in the carb mounting pad to get vacuum for power brakes and map sensor, or did you drill it somewhere else, some pics would help of how you have it setup, thanks a lot cuz I have to do it this weekend, the accufab tb should be here next week and I wanna put the intake on this weekend so it's ready to drop on and fire her up by next weekend!!!!! 
Also, I hear about people running spacers under the throttle body, would you guys recommend it and what exactly is it's purpose and how tall of a spacer would you recommend, right now it would be just the accufab sittin on the intake till I get the plate kit for it.

You don't have to drill a hole anywhere or you shouldn't.. The throttle body will have provisions for the MAP sensor and the brake booster hose.. Or it should anyways.. My Accel t/b does.. If you look at the pics I posted in the other thread you will see the MAP sensor coming off the front of the throttle body.. It has a port on the back side also and I just had a barbed fitting in it with the brake booster hose clamped onto it, but now its got a brass plug in it since I switched over to a Strange Master Cylinder which I highly recommend..
