Impossible to cam?
I've got myself a 1993 F150 with the 5.0/e4od combo. When I finally got fed up with the slow loss of power from the original 5.0 motor, I swapped it with a recently rebuilt 5.0 from my wrecked 1996 F150. My motor swap went perfect. Since then I've grown to have a thirst for a bit more power... I've been wanting to just throw in a beefier low-mid range cam, heavier valve springs, and heavier torque converter. I haven't started preparing my master plan due to the fact of I have no idea what cam to get! Haha!
If any of y'all could give me some assistance or even school me if you need to I'd appreciate it!!

The roller cam in the '96 donor is pretty good. Add some 1.7 ratio roller rockers, long tube headers and a high flow converter....good to go.
You could have swapped in some GT40 heads for some extra HP.....

More lift and slightly changes the ramp up curve. Cheap HP without changing the cam. And it's Speed Density compatible.

No. Not necessary but would boost HP/Torque without a cam change.

Crane Energizer Pedestal Mount Roller Rocker Arms 44746-16
$240 shipped from summit.
All you require is:
plenum gasket(fel-pro MS93834)
valve cover gaskets(fel-pro 1684)
And some vaccum hose if u crack any plastic lines on removal of plenum and V/Cs.
Remove the hidden t30 bolt at the base of plenum between the gap in the runners by vaccuum tree. You can put the socket thru the bottom of plenum and feed an extension thru top.
Some benefits include less friction,faster revs,and some lift

If you want an opinion.
The higher lift rockers are a waste of money, and ultimately a waste of your time.
Cam swap would be more ideal but just as much a waste of money and energy. Is 5~10 extra HP on a 200 HP engine, really worth $250-300 and your time?
I'd shift focus to the big picture, intake, heads, higher compression ratio, an ideal cam and mass air swap(although not really required). Start saving cash for a real change.
The right cam for a stock engine, isn't the right cam for a built engine, and depending on what's ultimately done, you may find 1.7 rockers to be a hindrance, not an asset, so like the cam, Id wait, and aim for the big picture.
If you really want to apply money now, that will improve your truck performance noticably and still be of use when you put a real HP engine in it, then direct attention to the trans and axle gear ratios. Tighten up the trans, valve body, (id wait on the stall converter, until you figure out the new engine), get some numerically higher gears in the axle(s).
