Hei distributor for tbi sbc

[Richterwreck]

Help.... I recently purchased a firestorm HEI distributor for my 95 Tahoe. After I purchased it I realized that there was no vacuum advance on distributor that stock. Can anyone help me to understand how to wire in the vacuum advance HEI distributor in place of stock distributor.

Find a vacuum source on the intake manifold or T it in to an existing hose.
