Will this cam have more vacuum in a 350

I rebuilt a 327 sbc, ran it for a while with a edelbrock performer cam, wanted a little more cam bought a engle ep-22, had good torque good top end but less than 10 on vacuum, Would this cam have more vacuum in the 30 over 350 i have in the nova now, car is a 73 chevy nova street car, motor has been decked in the past cant see engine I.D. on passinger side block i am running 416 305 heads 184 150 valves, port matched, thin head gaskets car runs good now, but i know it would run better with the ep-22, just need to know if it would have more vacuum? Thanks Wormy.

I`m guessing it would have slightly more vacuum due to 27 more cubic inches. As for performance, the 305 heads small valves and not so good intake ports are killing all the benefits of the bigger cam, and especially will with more cubic inches.
