Camshaft Selection

[Gwyn Reedy]

I have the 402 BBC out of my 72 Cheyenne pickup torn down for a rebuild.
Dang oil pump inlet fell off and the bearings got fed a mixture of oil and
air...

The engine is not very badly damaged. Taking the crank in today to see what
it needs done to it, but it doesn't look very bad at all.

The cam shows a lot of wear. Looks like the original cam with 70k miles on
it. Some of the lifters are starting to get concave a bit too.

The truck is used for running errands around town, and from time to time
pulling a heavy trailer. The trailer is 6000 lbs empty and up to 14000
loaded. 3.08 posi rear end and THM-400.

Wondering what cam to put in it. This is an oval port (passenger car type
heads) with a low profile Quadrajet manifold, standard cast iron exhaust
manifolds. Need low end torque, not horsepower.

I'm wondering if any of these 'bottom-end torque for 4x4 off road use' cams
might be a good choice or should I just put a replacement factory cam back
in it?
