Cams How do you choose one?

Ah so you are the 'chassis guy'.... so you appreciate good handling and cornering. So you know that good 'grunt' (torque) at the wheels is part of the whole package. Looks like it with the suspension upgrades you have. (I see Bilstein's in your future, if you don't already have them LOL). I remember going through all the anti-squat design stuff that you undoubtedly know, and concluding that if you are turning both L & R on roads that go up and down, and braking as hard as accelerating, all that stuff works as much against you, as for you.

Yeah, RRR's example has some unknowns, in that we don't know the trans, or TC stall speed if an auto, and defining 'fun car' varies with us all and is subjective. If 'fun' for you is in a straight line and you have an auto, things change for the engine design. So that is why the application info is so important. If you want to corner hard on the street, then that makes me think the wide torque band approach is all that more important. (Though I don't know how curvy and undulating your local roads are.)

It may seem idiotic to have so much torque at the rear wheels that you spin the tires at half throttle in 1st, but when you get 2nd and or 3rd in a manual trans car, all that 'excess' torque at the wheels suddenly gets whacked by the change in trans gear ratios. So you gotta have gobs of excess torque in 1st to end up with adequate wheel torque in 2nd and 3rd, where you really need it to throttle steer through the higher speed corners.

You're all over the map for the RPM when you power through an unknown radius corner on the road or in a rally. You just can't 'rear gear' optimize it like on a circle track to work with a narrow torque band in the engine. It's either a lot of gears or a wide torque band in the engine.

Hope I have not digressed too much....

(Edit to add: Oh yeah, I am just getting into the snowmobile thing at age 65 LOL)
