To Vacuum Advance or Not to Vacuum Advance

You can mod your Vcan for more degrees by removing a buncha material from the stops. I started with a 9* arm and ground enough off to get 22*. Another member,TrailBlazer got 24*. My small-cammed 367 (230/237/110* ), comes up on the vacuum pretty quick, and I have the Vcan set to bring it in as fast as it is able, and that is working pretty darn nice for my combo.( manual trans).
I cruise at 65=2240* ; on 28 mechanical, plus 22* in the can, and up to ~8 with the dial-back timing device. That comes to 50 to 58*, with aluminum heads at 207*F minimum coolant temperature.
