The vacuum block is bolted to the top of the throttle body on the 1986-1987 Turbo Regals.
Since these were originally plastic, many are now bowed down, cracked or warped due to age, heat and tightening over time. This can lead to vacuum leaks. Our version is made of aluminum to match the appearance of the throttle body and upper intake plenum.
NOTE - We offer two versions of this reproduction vacuum block:
Part #6796 - 1986-1987 Turbo Regal - Stock Vacuum Block. It is exactly like stock.
Part #6797 - 1986-1987 Turbo Regal - Vacuum Block (with extra port) with extra vacuum fitting for vacuum brakes. It is identical the Turbo Trans Am and has an additional vacuum port on the driver's side for a vacuum line for vacuum brake conversions.
Each vacuum block comes complete with new stainless bolts. Each vacuum block has five metal screw-in fittings, so they will never break or bend.
Because your stock block is plastic, this is something you will want to replace soon. Most of them are warped by now.
NOTE - Reproduction Vacuum Block Gasket, part #6839, is included.
