Per Summit's Q&A/reviews on the 60244:
Will this Cam work with Power Disk Brakes without a Vacuum Canister?

1 Answer:
It will depend on displacement. In a 350" Pontiac, doubtful. In a 455, most agree it will work. I had one in a 76 TA with a 400 and it worked, but not as well as stock, with my power brakes in a standard transmission and 4:10 gears.
