Welcome to the forum will
Search the truck and auto trade magazines, local and far, for Ranger V8s
There are people that sell their Ranger V8 swaps, loads of upgrades for the Ford 302 engines, not so much for the 4.0l SOHC which is what you have
You can look here: Tom Morana Racing Engines
As said you have the SOHC(OHC) NOT the 4.0l OHV which came in 1990-2000 Rangers
Super charger is about only thing worthwhile , and stuff WILL break unless you do the whole engine with upgrade parts, lol.
Its only money, and "better in hock than stock", lol
But "there is no replacement for displacement" so getting a V8 Ranger is a better way to spend the dollars IMO

Problem with boost is that you try "just a little more", lol.
So yes with under 5psi boost it should be fairly safe, some say 7psi, but the crystal ball is never very accurate.
You know its 1psi too much when something breaks and not until then

I am getting a exhaust and headers done within the next month and already put a cold air on. Just live in Montana and need to be able to go through these mountain passes without bogging down to 60 or 70 miles an hour
Yes, the thin light air above 4,000ft does take the power away from normally aspirated engines, so turbo or super chargers are about the only help there is for that
Air:Fuel ratios are by WEIGHT
Gasoline is 14.7:1 ratio so
14.7 POUNDS of air
to
1 POUND of gasoline
14.7 grams of air to 1 gram of gasoline
At its best ratio gasoline releases XXX amount of power per pound or gram of gasoline burned
So with the lighter air at altitude you can not burn as much gasoline so power drops down
Boost forces in more air so more gasoline can be added, so more energy released
Higher displacement engines have more power because they can pull in more air so more gasoline can be burned and more power released, simple as that
