Marcus the 2x4 intake is a 65 427 lowriser the shorties are 60 352HP which are basically the same as 390HP and 406 except for the choke heat provision for the multi carb setups(the carbs sit on the intake backwards so choke heat comes from the driver side)60 have it on the pass. side only while 61& 62 have them on both.The bell you need is casting # C6OA which is the 390GT and 428CJ piece.Cast# C5AA may work if the Z bar pivot mounting boss doesn't get in the way,it could be ground off since you won't need it in a unibody car,it was used in 65-up galaxies.Thje C6OA bell looks identical to the C5AA bell except that boss is machined off on the C6OA.

SK #s were used on prototype pre-production and experimental parts so that may explain the pressed in plugs some kind of experiment?

Are these cast headers?

Rick most 390,s can hang for a very long time with up to 400 hp with stock parts but how fat is your wallet a 390 car or pickup truck is basic the same engin the ft truck engins as in the hd truck searies moters are good for some parts like the blocks rods and steal cranks but most need machine work to fit auto aps i try to stay around 300 to 400 hp moters that last me 100000 miles +

If your tach hooks to the ground side of the coil then it will still work with the petronix. I wondered the same thing but after installation my tach still works fine.

Unless I am mistaken all C6 are forward valve body unless you add modification like TCI reverse valve body.

A reverse pattern valve body changes the pattern from PRND21 to PRN12D. I think you're referring to the actual shift lever arm and rod. They are different between column and console shift transmissions.

As to your question...you need a forward shift pattern shifter since the reverse shifter is a very different thing.

Have you tried Mr.F's decoder?
If that dosen't work, try this site. It should help you narrow it down.

James a block with a casting #C4AE-A does fall into the group of 427 casting #s but that # was also used on 390s that had the bosses for crossbolts.If you can't take the heads off to check the bore size then look for these external identifiers 1.crossbolts above pan rail 2.extra oil pressure relief valve in back of block above rear cam soft plug 3.Lack of lifter oil galleys in back of block 4.There will be the letters HP cast into the block(as well as stamped in the area you mentioned)in at least one spot usually in multiple spots.If all of these are not present I would be leery of it because the C4AE block is capable of recieving crossbolt mains even if it started out as a 352 or 390.The lack of lifter galleys and the extra oil relief valve are good indicators of a 427 block though,I have seen one 406 service block that was a C4AE & had all the above items but it may have been a 427 block machined with 406 bores.The C4AE -6090-G heads are 390 heads,the casting #s are sometimes almost impossible to read.Neither of the carbs are correct 427 carbs.Matched dual quad carbs will typically have consecutive list #s.The casting date you gave sounds a little late for a C4AE block but you never know what Ford would do.Hpoe this helps.

no, the factory FE manifolds will not clear the frame. But there are tube headers that can be bought, but they run outside of the frame then the header extension ducks back under the frame and you can connect a exhaust system to them.

I'm not sure of the rods, but they sound like the skinny 352/360 jobbies.

You can verify by looking at the crank flange. If it's got both a square notch cutout and a half-circle cutout, then it's a 360. If it's only got the square notch, then it's a 1966-later 390 crank.

The 360 engine got 390-4V pistons to drop the compression. Some were marked "390-4V", other identical pistons were marked "360".

The 390 pickup truck engine got 410 pistons to drop the compression to prevent pinging when hauling heavy loads long distances. Compression for both the 360 and 390 pickup truck engines were around 8.5:1

Shoe.

what numbers are on the crank most of the time wen the piston says 390 it,s a 390......
