Roller 302 with archaic components?
I have a '78 F150 with a 302 that burns oil constantly.
I'm considering yanking a roller 302 from a newer Ford and dropping it in and reuse the stock stuff (2150 carb, manifolds, etc etc).
I want to know if I will run into issues with wanting to use a mechanical fuel pump with a newer block that may have been fuel-injected?
Or is a 302 roller block too new for what I want to do? I know nothing about the newer blocks...

You will have to run the earlier timing cover but you should be able to get it done just by swapping stuff off the old engine. I helped with a project like this, but that engine had early heads on it so I can't tell you for sure on the intake fit but it should be ok.

At most you will have to transfer the mechanical timing cover and the pump essentric that bolts on the front of the cam to make it work. The intake will swap no problem as will the distributor but it will need a steel drive gear for the roller cam.

Oh, this is turning out good...heh, heh.
Would I have to change the oil pan to the early style as well in relation with the timing cover?
I did some reading and ran into the 5.0 HO engine. I find the '85 5.0 HO should be sufficient - I get a free 4V in the deal in addition of the roller. Thinking of going this route, if I can find a '80s Mustang around here...
Although, the '93 would be sweet...but I doubt I could find one that easily.
Lastly, I read most 302 heads are way too restrictive from factory. Fact or myth? How does a stock '78 measure up?

Yes the 1985 Moustang engine might be good, its distributor may possibly work with your existing Duraspark. It has forged pistons.
It might be worth trying to find a later Exploder with the GT40 heads.
You might have to use your old oil pan as well depending where the dipstick tube is located on the new vs. old engine.

It's all relative. '78 was the smog era so all motors has puny cams and cylinder heads with larger combustion chambers to lower compression. A stock '78 truck 302 was rated at 140hp, swap on some late model heads and upgrade the cam and you can nearly double that.

Perfect.
Beanscoot, the dipstick is on the passenger side. I think it goes in the block, but I don't know for sure. It is a 2WD F150.
I found plenty of later 302s in junkyards...the only problem is, every one of them were from the CFC program. I cannot find a 302 that hasn't been destroyed.
It boils me to see PLENTY of GT40 and roller 302s, sitting there totally unusable. Guys with Mustangs with 302s in them are already built.
Ah, i'll update when I actually find a good candidate.

I take it the "CFC" program is the cash for clunkers... so the junkyards have to destroy the parts? That sounds rather vindictive. You'd think they could simply put the serial numbers of the vehicles on a list to insure they just can't be licensed again.
I guess the vehicles are thought to be evil and must be cruelly punished.

Pull the GT40 heads off of a C4C explorer, chances are they are still in good shape. All the Sodium-Silicate does is turn the existing oil into jelly so it doesnt provide any cylinder-wall lubrication and the engine freezes up. In the amount of time it takes to freeze up the engine (few minutes) the heads are exposed to very little death juice. I have seen a set in person that looked fine.

That's all - don't want it to turn political, not allowed.

Don't know if I wanna take that chance...I've seen some CFC cars that refuse to give up the ghost easily after being injected with the death juice. Smoke, overheating, the works.

Yeah, with the AC program, I felt the same way when I walked through a JY full of perfectly good engines ( the AC motors weren't tampered with, they just had to be crushed with the cars) and not being able to buy any of them or even get parts off them.
