I wouldn't change it.

I had a crower 16332 w/ 260 @ .50 and loved it! I then had a second motor with a milder hydraulic cam and comparitively it was blah, blah and more blah - never again. In fact, when my side oiler was rebuilt we used a .691 lift solid roller (Comp Cams) and it idles at 800 rpm's and purs like a kitten and roars like a lion (7600 rpm's!).

With a hydraulic lifter set up your springs can't be to extreme because if they were your lifters would not pump up and valve float would be induced. For what it's worth it seems like something could be done to get the car to run better - mine was fine with a very similar set up. Best wishes.

One more thing - throw that holley as far as you can and buy a Mighty demon 825 cfm from Barry Grant. It's a mechanical secondary unit that runs circles around the holley I replaced it with. It's more adjustable (four corner) than the holley but I don't know how it compares to the Proform.
