Cam advice for more torque from 340

I would love to hear some opinions about a new cam for my 340.

First, the engine is 10.5-1 compression.
Stock X heads with factory rockers.
Currently has a Crowler Cam with 285 dur, 480 lift, 110 deg. (I was told this by the previous owner however I can't find a crowler cam with these specs.)

This is in a 69 B Body and it's only used on the street. I'm looking for more low end torque. I don't race so having my power in the high RPM range does me no good.

I was recommended a Comp XE 268. Not sure if there is something better.

Thanks
