Non-mopar cam question for towing

[DocMel]

Folks 

Outside of my 71 Cuda, I have a chevy 350 I have had for years.

I need a cam recommendation for my 350.  I'm not cam smart guy, but I need a cam for towing. 

I have 3 grinds in mind:

Cam #1
Duration at 050 inch Lift: 214 int./224 exh.
Advertised Duration: 288 int./298 exh.

Cam #2
Duration at 050 inch Lift: 224 int./234 exh.
Advertised Duration: 298 int./304 exh.

Cam #3
Duration at 050 inch Lift: 234 int./244 exh.
Advertised Duration: 303 int./313 exh.

Which of the above cams is the best for towing ?

Cam #1  looks best. What are the rest of the specs? Lift, LSA etc?

even #1 may be too much duration for towing?
