I plan on converting to disk and power brakes. Will I have vacuum problems with power brakes when my 347 is in and going? My cam lift is 560. I have heard there are units that run off your power steering. I have also heard there are electric units. Were there Lincolns that had this setup? Maybe I can do an affordable conversion from parts out of a junkyard. Or, can I just use a vacuum canister?

Cam duration and overlap will affect the vacum, not lift.

 

Longer duration and more overlap(lower LSA) means less vacuum at idle

 

electric vacuum pump and resevouir........period
