Is this to much cam

Best bang for the buck with those tires is more gear and a 2800TC, and forget about that cam.
How tall are your tires, 29s? 3.55s is not nearly enough gear. You want snappy? You need the equivalent of a 12.34 starter gear with 24s. That would be 3.79s with 29s, I would round up to 3.91 with a 318. and don't forget the minimum 2800TC.
The 4bbl and duals are bang-on. Put springs on it to hit at least 5200, cuz the 727 will suck the Rs down to 59% on the shift which being 3100ish. Anything lower than that, and the poor teener will be struggling, cuz with 29s and a 3.91, she will be pushing air at 45mph. Second will pull to 75, and third;109mph.
The 3.91s will cruise at 63=3000
You can put any cam in there you like but the performance will not be there to the extent that gears and a TC will get you. In fact; I can bet you a dollar you'll be back, crying about how soggy the bottom end is. Then someone will tell you to put 3.91s in, and at least a 2800TC. And then you will have what you want; a snappy truck with a little lope.

As for me, I would not install any slow-ramp cam.
As for me, I think I installed 360 springs to cure the lifter pump-up/valve float, with a little extra shimming.
I have an 84 D-100lb.

EDIT
I got mixed up, again. That photo in post #13, is not gerty's lol. So gerty, what size tires are YOU running.
