Billet Vacuum Block

This is a "BILLET ALUMINUM THROTTLE BODY VACUUM BLOCK" for a 1986 or 1987 Buick Grand National, T Type, Turbo T, or GNX 3.8 liter turbo V6. This item replaces the stock cheap plastic piece. 

When my supplier first showed these to me I wasn't really thrilled with them BUT, now that I have seen them mounted they actually make a lot of sense!  You now have 6 ports to plumb your vacuum lines how you want them.  Of course with the extra port over the stock one you can run one line to your vacuum brakes if you have converted from the troublesome Powermaster setup

Another benefit is you lose 5 potential areas for a vacuum leak.  No more short lengths of rubber hose that connect to the metal lines used in the stock configuration.  You can run a line from the driver's side of the block right to your fuel regulator and use the remaining port on that side for the EGR, then you only have one line to run under the throttle body if needed.  No longer will you have to struggle to connect the bracket under the throttle body.  You can always add different fittings as needed as shown in the pictures of one installed..

Our Vacuum block comes complete  2 stud bolts, and a gasket. This item is made in the U.S.A. and has a billet machine finish to it.

We have decided to just sell these WITHOUT any of the fittings,  Since everyone has a different was of plumbing things up it is easier for us if we sell it this way.  The ports are all threaded 1/8" NPT, one hole is drilled larger for vacuum brakes.



This item is made in the U.S.A.
