Would it be easier to convert this to an electric motor set up, or to wire in a little vacuum pump?




I think you need to go thru the vacuum system and bring it up to snuff if it's stock 50 year old components?, running a reserve canister?, factory style?....

Your running a 509 lift with 292 duration and having problems with sufficient vacuum? whats manifold vac at idle?, automatic transmission?, power brakes?

My Daytona is running 520 lift with 284 duration, 6 pack, manual transmission and about 10-12 inches/vac at idle, dual diaphram Bendix booster w/4 wheel disc and I have plenty of vacuum to lift the Daytona doors which have to weight 2-3 times heavier than stock 68-70 Charger doors, and my light's vacuum system is basically the same component wise as yours...



So Its a cast manifold basic stock rebuilt 70 440 sixpac engine and hemi 4 speed out of a70 challenger. I have installed FiTech efi six pac on it. isnt fired up just yet, still waiting on a few loose ends.

509 cam, and very stock everything else.

Power brakes
