any !. Well the 87 up will have efi friendly cam. But the 93 down 302 had old order where your 302 has same as 351. So you would have swap cam or repin or rewire injector harness. If its a MAF there be few more. I have a 93 in a 94 .
So if want plug and play find a 94 and newer.

Yes.. any 302/5.0 block will bolt up, and any '87 or later block will be compatable with the stock Ford roller cam assembly in your '94 block. If you don't get a late model block it's not the end of the world though, there are lots of better-than-stock cams in both flat tappet and roller versions that are also compatable with the stock EFI system, and if your truck is mass air you have even more cam choices.

The cylinders won't fire because of no fuel or no spark. If the injector is OK, (check by swapping them with another cylinder) then it must be spark. Check proper wiring, wire routing, plugs, everything. Hopefully the block came from a truck and not a car. If it came from a car, you have the wrong firing order.

Yes i think it did.
So im thinking the firing order would have to be the 15426378 and i would have to make the injectors fire in the same sequence.
Am i thinking in the right direction.
If not then what

OK the engine came out of 1989 ford crown vic
The deeper i look the more i find cly numbers 1/2/6/8 dont run
I thought at first just 6/8 but now i find all four dont hit
Would the cam make the differance
I am stumped

Is your '94 truck mass air by any chance? If your truck is speed density it fires the injectors in batches of 4 and the cam firing order won't matter. If it is MAF it fires the injectors sequentially in the 13726548 sequence, but the cam in the CV motor has the 15426378 order, so you need to change one or the other. I'd suggest changing the cam as the stock CV cam is pretty sad anyway.
