Cam choice for low compression motorhome 440

In
The OP said he don't want a choppy idle, so why a thumper cam ?
Id say comps 265deh cause of the manifolds.
In truth, if a performance gain is to be had by the proper cam choice I'm sure he would take the idle with it. Lol, he always comments on the sound of my 408 which gas a definite cackle.
