Another, Damn it, horsepower guess ??

This is coming to me, I think a an already package deal. I am kind of thinking that less will actually be more.
What I really want is to have it pull like a freight train from 2500-6000
I could sell the roller and rockers get a flat tappet cam and still have money left . From what I can tell this custom groundvcam with rockers retails for around 1200. I could get at least 550 for it and that would definitely get me a cam kit, cam, valve springs, retainers, locks, pushrods , lifters etc.
Are you going to run an automatic ? Because the cam you want & the converter you'll need will blow right past 2500-3500 & probably 4500 before it even gets moving & not slipping. You could get away with alot less cam to do what you want something in the 250s duration at .050. I'm not a no2 guy so I'm not sure how that will work but I'm taking a guess with the cam you want to run letting in that much no2 & fuel it's destined to be a broken block or rods or something in no time.
