Finllay getting to the point of firing the Ford. Have a Holley street avenger 570cfm carb, 1” spacer on a B manifold with 57 distributor. What I am wondering is the vacum line from dist goes on side, but do you need to have a source for the full vacum connection on base? Should source be direct form manifold or can the connection on top of fuel pump workable if needed? Any other tips or trick for setup to start or for tuning?
