Vacuum hose routing
Ive got a 74 454 with a Holley 4150. I just want to make sure my hose set up is right. Im not running the AIR set up and Im running electronic headlights. Ive seen the factory diagram but Im looking for something a little more simplified. Im just curious what everyone else is running. So if you have any pics it would be very much appreciated.

74 350 and I run the hose from the vapor canister and "T" that to the PCV and it connects to ported vacuum.
Brake booster connects behind the Q-Jet.
EGR pluged and not used.
Auto transmission connects to back of maifold
Heat controls also connect to back of manifold
and head light connects to 3rd port on manifold.
Distributor vacuum can direct to full manifold vacuum port on carb.

It dawned on me that I should explain my set up. Im running a Hollley 4150. It only has 3 ports. The PCV is running from the big port on back. on the smaller port I am running TCS off of the second port (this one might not be correct). I am running the automatic choke and timing advance T off the 3 port. Im running the heater off the manifold, and the brake boost off another manifold. Im sure there are multiple wrong issues with this set up, so if so Im a big boy and can take it.
