using mechanical pump?

Ok, so if one was going to drop a 360 mag from a truck into a older car, and was shooting for a "similar" motor like the 300 horse power crate motor, what cam (part #) would you order to have the mechanical fuel pump eccentric? Is there a cam that would run as smooth, work well with stock magnum valve train, and perhaps add an extra 15-20? Say, a 320 horsepower 360 magnum?

Here's a good street cam and would be .512 lift 1.6 rocker with perfect geometry.

As RRR said Oregon Cam regrind would be much cheaper.
