What pistons are in it? That will be a determining factor.
Also I would change the stock rockers (if you are still running them) with that cam. they are only good to right about .500 lift. I ran a cam with .504 lift and had no issues, but I think I was at the outter limits and probably pushing my luck.

That's I'm that sure but I'm guessing a lower compression type.but I know they are new or near perfect shape. I know I'm not going to be pushing the motor past 5000. just want a mild cam with great torque for the street.

Then I'd do a single pattern cam, i.e. 215/215@.050 or similar.
