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.
I run a stroker solid roller 236-242 @50 for the street trust me it runs like a freight train 345 rear lsd 904 3000 custom stall off idle to 5700 . It’s quick and the torque is a rush . Shifting @ 4500rpm keeping it in the torque band your hauling ***. No need of spray unless your on the track .
