347 stroker???
So I have a 302 EFI in my 90 F150. I've been reading on building a stroker using that same engine. Engine's not worn out, just truck is real slow. Not a problem but kinda scary merging onto the highway. But anyway, what is involved and can it be done for cheap (I have college to pay for!) I've heard you upgrade cam, heads but am still confused

Before you start tossing money into an engine rebuild take a step back to subjectively figure out where you currently are. When was the last time you did a tune-up on the truck? What size tires? Any other mods?
Plenty of lower dollar modifications you can do before going with a stroker that are easy on the budget and will yield reasonable returns.

Forget the K&N, it is worthless on an otherwise stock engine. What kind of plugs, wires, cap and rotor did you use? Those 32" tires are the most likely culprit of robbing you of power and mileage.
Many here on these forums and others have had great success bumping the time up to the 12-16 BTDC range and opening up the plug gap to .055" range. AKA Sixlitre tunep. You need to figure out what the gearing is on your ride. Anything less than 3.55 is an absolute minimum BEFORE swapping on larger tires.
An also well known bottle neck is the factory y-pipe and converters. Swapping those out for a high-flow version is the best way to unleash some power after doing the timing bump and tune-up. For added performance long tube headers are the way to go along with a custom exhaust. For me I am happy with a Bassani 3" y-pipe, 3" converter and single 3" exhaust out to the tailpipe.

Gears sound good with the tires you have. Definitely look at getting rid of the factory converter and y-pipe or go with long tubes and custom exhaust. Still sounds like something is amiss here. A timing bump may be in your immediate future.
