New torque converter?? (and cam question)

Moper:
Took liquid measurements before the engine was put together, and if I remember right it was pumping out about 145psi or a little under at about 5k miles. I'm not certain of this number though, and the car isn't in the position to be cranked on

And I guess I might as well call a few of the places and get quotes on converters.
And if I did go with a higher stall converter, how bad would something like a 2800-3000 be on the street if I was recommended one? (which I kinda doubt, but for just in case purposes).
