Just because you have all the specs on paper don't think you'll be able to tell what the performance and sound will be like. If the cam doesn't match well with the rest of the parts it won't perform it's best and the sound has alot to do with your exhaust system and a little bit to do with the cam. I think best you could do is post your specs and maybe have everybody you know post theirs and a sound clip so you can hear it first person. Get some good ext speakers hooked up to your comp.
