New to the Y Block world somewhat, I am just opening up a 56 312 in a 56 T-Bird that has had the the Carb and Dizzy plague for year with my inlaws, car is now my wife's and it was her mother from new so I need it to be dependable restoring to a driver car to USE. I thought I would go with the Mallory Tach drive unilite and change the intake to a 57 ECZ9245B and use a 4160 465Cfm Holley to hopefully make this engine come back to life along with just needing to be gone though anyway has two low holes and no rear main left.

Big part of my question is there is no vacuum advance on the new Mallory Unilite electronic Ign. with the mechanical Tach drive, not being from the electronic ignition world, how will this work with the stock 312 and Holley on the low end and actually in general for performance with this unit in a normal driver and interstate car, School me please on the install and operation of this Unlite.



Thanks guys
