I put a 350 horse cam in a 350 with 8.5 comp, and it would not idle at all. That cam is stock for a 327 or 350, and has .450 lift and about 268 duration. But it is for 11-1 comp, and would not run below 1,800 rpm.
I put in Rhodes lifters, and then the Vacuum went up to 20 in drive, at idle. Instant throttle response.
14.6 sec and pulled the wheels? That is low end torque.
