I know Dick Boneske runs a fairly mild cam in the Tri-Power 428s powering both his and his wife’s 1964 GTOs, something around the Summit 2802 or a tad bigger like the Crower 60243:

A quiet exhaust system is a big plus when you’re cruising along with the top down. Exhaust noise with convertible cars is much more apparent, you hear a lot of road and exhaust noise whether the top is up or down.
That makes sense. I would like a little lope to the idle but I dont need anything ridiculous. Im not sure where that falls as far as lobe separation? Will 112-ish have a nice idle?
