Do you need to go back with the emissions stuff? If not, it is pretty simple:
Edit: With a later engine in a 61 truck you probably don't need to pass emissions. Duh.
- Ported vacuum, meaning no vacuum at idle, goes to the vacuum advance on the dizzy
- A "tree" screwed into the back of the intake manifold hooks to:
- Large hose to brake booster - if you have power brakes
- medium hose to the cruise control - if you have it.
- Small hose to the little plastic "manifold" on the firewall, which serves:
- Small hose to the HVAC controls
- Small hose to the auto tranny - if you have one.
