I have An Offenhauser intake with 3 Rochester carbs. I have a power brake booster, 350 turbo trans and a Vac adv dist. The center carb has a fitting in the base plate and a nipple in on the top side. The front carb also has a nipple on the top side. Not sure but there is about a half inch fitting at the top rear of the offy intake. I need to know the best place to hook up the power brake booster vac, the dist and the trans shift valve. Thanks!!!!
