got a Dominator intake on there now, and an adapter plate to go to a regular holley 4150 pattern.

only got one vacuum port.

gonna take it off, and drill 2 more, for a total of three:

-Crank case vent
-tranny modulator
-power brakes.

has one in rear, gonna do one on either side.

anyone got the tap & dies to do something that big?

you will prolly want to do NPT thread for vac lines into the intake for the crank case vent and brake booster being they are larger so something like a 3/8 npt

Lowes sells 1/8. 1/4, 3/8 and 1/2 npt taps.

I also have a 1/4 npt if you need to use it.
