what is the end goal? Track times or a fun car to drive? If you're wanting track times go with a solid roller and forget those two cams.
Ever tried either of those cams with a stock gear or did you just read this on a forum thread somewhere and make an assumption?

i went from a 224 to a t-rex and gained nothing, maybe it was in my tuning? idk , IMO id rather go with a smaller cam or have a custom one rather than a huge *** off the shelf cam thats curve is nowhere in the neighborhood of what your wanting to do with your motor.

I agree and disagree with Sigforty. I would also suggest the F14 over the F15 but I think driveability is likely the same (all depends on the tune). You would probably make more peak power with the VRX but more under the curve with a Futral cam.
Check out some dyno graphs of the big Futral cams. They are nothing like most big cams. They make excellent low end torque.
With your car already having a 231/237 you probably have more to gain by going with a Futral cam since you'll pickup low end. Otherwise I dont know that you would even notice a difference with the VRX.

i had an FMS 235/237 599/602 on a 112. stock 6.0 with all the boltons through a catback ran 7.0 1/8 mile at 3360 pounds. same setup with stock valve patriots went 6.90 at 99.35 1/8 mile at 3400 pounds.
cam didnt chop hard. drove well with my big converter. never sounded fast.
ive heard 224 cams that chopped harder.
its exactly what i wanted and it performed, IMO.
