I think if would run well with 11:1 compression with some cam advance.
I would not run Vmax lifters on it. It would gain some idle vacuum, normally the lash is .035 when using Vmax on a mech cam, versus .022-.024 normal. Some vacuum rule classes run Vmax on mechanical cams. But by 2 or 3000 RPM, most of that lash is taken up by hydraulic action of the lifter. After the lifters pump up your throwing the dice to see if the engine will like it or not. If you dont care about the idle vaccuum your better off with a mechanical lifter and just tighten up the lash. Whatever the Vmax does full throttle, your stuck with it.
Here is a similar very similar profile to that Crower. It is an old General Kinetics 316M (280*@.050, .3925 lobe lift) mechanical cam if you want to see what Stan is talking about, how lash effect a profile compared with a hyd lifter. Divide the lash by the rocker ratio, and see when it lands on the ramp. Can do it at any point and compare to a hydraulic.
