Nice looking car and engine bay. I've seen a lot of clean cars but when the hood was popped open - ugh.

Great looking engine bay!

To all- I see the vac advance canister is capped off. Would he be better off with it connected?
I didn't use vacuum advance on my 355. At 36* total, it was maxed out. I tried vacuum and it was ping city.

It depends, if the mech advance is tailored in conjunction with the vacuum advance that's been limited to the engine/vehicle combination, in many cases, then yes, the vacuum advance is better off connected.

If it has not been limited, and it adds in another 20-23*, then no, it should be left disconnected. Vacuum advance helps in most cases in high performance street/race applications. Serious race only, locked it is dominant most of the time.
