Hey Jaycrow,
If your interested I have a fully rebuilt 390. I live in NJ but will depart with it cheap if you need it. Shipping can't be all that bad.

I gos a question. Did the 302 and 302 HO use the same crank despite having different fire orders? Or was the main reason for differing order the camshaft?

Yes, the two engines have exactly the same cranks.

The only major factor in firing order is the camshaft. It determines where the valves are in realtion to the crank.

The only major factor in firing order is the camshaft. It determines where the valves are in realtion to the crank.
The position of the piston in the bore HAS to be at just before TDC, and both intake & exhaust valves must be closed. That would make the crankshaft throw/piston position a VERY major factor also. Since the crank from an HO engine has a different part number then the crank from a NON HO engine, I would say that the the 2 cranks are NOT exactly the same.

Steve, I'm pretty sure that the HO cranks were forged, although I'm not certain, and this is why they have different part numbers.

HO cranks were not forged.Camshaft determines firing prder.That's why you can put an HO/351W cam in any 302.A big difference in cranks was the balance in the early 80's it is different than the old 289-302.

Ford has always mix-managed powertrains to match availability, capacity, popularity, etc.
When the second gas crunch hit, car sales went south, FWD started into the mix, and they didn't need the FMX anymore so they closed that plant to save money. But the 351M hadm't died yet and they didn't have enough C6s (remember trucks were still selling okay) so guess what, the C4 became the swing tranny. However the 351M died after 82 (I think the FMX died after 1980, we may have built some 1981s, most of the guys I know who would remember are long gone) so there weren't many.
The FMX was around till at least 82. I had an 82 casting FMX last year.

NONE of the GT/HO cranks were forgings. And they used the same casting as the non-HO 5.0's. The later 5.0 crank's casting quality is so good that they look like forgings, but they're cast. The only forged 302 cranks from Ford in production cars were the Boss 302 cranks.

[QUOTE=Tang419]Let me help you out here, yes the 221 came in the 60's before the 260. Also, the first FE was a 332 not a 330 . The 360 didnt come before the 390 and 390's NEVER had an option for two 4 barrels.

what? the 390 had a option for 4bbl and most were made that way.

I've never seen one that had 2 four barrel carbs on it, I have seen a tri power setup on one, and I've seen 428s that had some kind of homemade manifold with two 4s on it. I've got a book that shows the 2 4s as an option, but I've never seen a factory manifold for one.

it was also very common to find the small bell C6 behind the clevelands in bigger cars like the montego, and torinos.
There was also a small bell 400 block built but they are rare, and to my knowledge ford never put the FMX behind the 351M but did put it behind a few 400s

Correct. I had a 77 T-Bird with the 400 and FMX, that cast iron beast.

If we can all agree that small block and big block are chev terms and has no right in a ford guys vocabulary, particular when describing ford engines than I'd be a happy happy man.

Whatever floats your boat. To me, small block Ford or SBF is a very common term, and refers to the 221-351W engine family and 351C. The same term (small block) is used with Mopar engines (273-360) also.
