Depending on money... Cam, Port and Polish, Supercharge, Turbo, etc.

Yes. Intake, heads, cam, and headers will wake up a stock 302 pretty good.

Just do the cam out of the truck. Arent you going to have to pull the motor? Do it then. And you should be able to find a used good set of GT 40 heads for less than $400.

How is this going ?

I have a 302 already but waiting to make “the list” of the parts I need, mainly a five speed/transfer case.

Just a comment, IMHO, stick to headers, and a better air filter on the intake, maybe a better intake tube but don’t go overboard for street/off-road use.

Porting and Polishing head for street use or lower rpm use is not a good thing.
P & P is too make the fuel/air mixture slip by faster. problem is the air/fuel is going so slow at low rpms that the air/fuel separate some and do not give you a good efficient combustion. By leaving the head OEM in the ports the roughness creates turbulence and keep the air and fuel mixed together and in turn a bigger and better boom in the combustion chamber.

Now for a Cam, if you get that far, get a short duration, with a little more lift than stock, w/ 1.6 Rocker Ratio.
Contact CompCams Tech Line, tell them what you are going to do with the truck, what you have done to the engine and the rpm level you want to run in; even if it is street use, they wil know.

I am just thinking out loud, so take the info with a grain of salt.

Good Luck with the project.

Oh ya, did you get it running ?

How far are you planning to go with the engine, rebuild (wise choice) either rebuild of the existing heads or look for a pair of the Explorer Heads, maybe cam (if used heads you need new guides, refacing of the valve seat minimum, refacing the head/block mating surface if needed, what will it be ?
The more you do, the it will cost YES BUT the less that will be a problem later on down the trail.

Another thought might be a short block or long block depending on how deep the pockets are.
The main thing will be a good running engine so before you decide on major mods like cam, intakes, headers and maybe new heads make a list of what you have, what you need and what you want and see where it comes out.
Things add up very fast and you can be part way through the project and run out of money, not good.

Do it right the first time !

It is hard to say what was going on.
Did the pervious owners do any work on it or attempt any work, did they happen to mention work that had to be done; a lot of “ifs” ?
I think you mentioned gas filled cylinders… may have been a blown head gasket or an attempted head gasket replacement, who know !

Once you take it apart you will know how things stack up.
On an engine that you do not know about, you can bet on it, that it will be costly to rebuild and to do it right.
Might have been easier to find a low mileage 302/5.0L from a JY and use it instead, I am not trying to discourage you on this project,.
It can be done and with determination it will be done, just thinking out loud.

Thinking here… a 93 or older Mustang (maybe others) had an engine harness that was separate from the Vehicle harness and would make a great adapter harness IF you were to go that route.

Thinking too much, good luck on this project, good one, even if you decide not to complete it you will have gained some knowledge taking it apart.
