110* will give it a noticeable idle, but your duration is low so it should be very tolerable, and it should make lots of torque.

The TFS stage 2 is a step up from what you were originally talking about, but it is tolerable in a 331 IMO. Personally, I'd favor something like this considering the combination of a very light-weight car, 331 c.i.d, and porting the heads.

I had a similar cam in a 347 in my '87 LX with 3.55 gears and it ran great. the bigger cam will go a long way towards livening that thing up with mid-range and top-end power, yet it idled great and had great driveability. The specs were a little more aggressive except for the wider 114* LSA (mostly to keep the computer happy as it was an EFI car).

In my opinion, a good gain in top-end power will be more noticeable (and fun) than sacrificing it for small gains in low-rpm torque in such a light-weight vehicle.
