Looking at this cam from VHP
DUR @ .004" 272*/280*
DUR @ .050" 210*/218*
LIFT .551/.551
OVERLAP 46*
LSA 116* "ULTRA TORQUE"
POWER RANGE 1500 TO 5800
How noticeable would this be over a stock 5.3 cam (does anyone have stock cam specs...i can't find them)?
The MAIN goal of the truck is to get the best fuel mileage possible at about 70mph (truck is mostly driven on highway) but I have a heavy foot, and occasionally pull a small boat. With the current gears, the truck RARELY sees above 2500rpm. I want the truck to be faster, but am mainly looking for more "passing power" on the highway. As of now, it needs to drop into 2nd gear to get out of it's own way. The top end on the truck is amazing, but it is a real dog below 3000rpm. I may mess around on the street every now and then, but it will never see a track.
With the cam, it will be getting a set of heads (mildly ported/polished set of 243's or equivalent)....some LTs...injectors...a tune
