I have a rebuilt 330(according to casting # on crank)engine in my 74' F-350. I also have a 390 laying around the garage. I have been told that a 330 was actually a FT engine. I was just wandering if I could take my 390 crank,rods,pistons, and put them in my block to give me a 390. I didn't know if there were any differences in the cranshafts between an FE and a FT. The 330 block casting #' is M6AE. (or something to that effect I don't remember excactly)

Also does anyone know what the HP and torque differences might be between these two engines?

Thanks again
Brian

 

I finally remembered the block casting is C6ME-A

 

I can't help you much, but I can tell you that the 330 was an FT engine and was only available in medium and heavy duty trucks. The block is a heavier casting, and I think there are differences in the cam and crank snouts, so FE cams and cranks won't drop right in without some mods. The FT engines also came with different heads and manifolds that supposedly are very poor choices for light duty vehicles.

If you have a 390 sitting around, why not just rebuild it and swap it for the 330? Is there something wrong with the block?

The 330FT has the smallest bore of any FE/FT engine at 3.875. The 330MD(medium duty) uses a standard 352 crank(3.5" stroke). As a matter of fact, it seems the only difference between the 330FT and any other FE are the FT heads - large chambers and small ports and valves.
The 330HD uses the forged steel crank with the larger counterweights, the thicker crank snout(1.75" vs 1.375") and the thicker flywheel flange. Also, the 330HD uses the thicker oil pump drive shaft(5/16" vs 1/4"), and a special oil pump and distributor to fit the bigger shaft.
In addition to this, you cannot use a tranny meant for an FE with an FT crank-the FT flange is too thick.
In short, if your crank snout measures 1.375", your 390 will drop right in. Rebuild the 390 and drive the other engine untill the 390 is finished.

Ps. The only positive way to identify the displacement of an FE/FT is to pull the heads or oil pan and measure the bore and stroke.

 

O.K. now I am confused.
the machinest looked up the numbers in his book and said that the crank was a 330.
the block is a 352/360/390/ block. with 4.05 bore (C6ME-A)
I have 390 heads. (D2TE-AA)
The engine has a 3.25' stroke
I bought a rebuilding kit for a 360/390. everything fit perfectly. cam, oil pump,timing gears,bearings, rings...
I took the 4-bbl intake off the 390 and it bolted up and works just fine.
I have been looking and I can't visually see any differences between the 330 and 390, other than crank.

Any ideas

 

You have a weird one. Simple math shows that a V8 engine with a 4.05" bore and a 3.25" stroke has a total of 335 cubic inches of displacement, not 330. As I understand it, the 330 FT had a 3.875" bore with a 3.5" stroke (same stroke as the 352 and 360 FE motors, and the 361 FT).

You may have what was originally an FE of 360 cid (3.5" stroke) or 390 cid (3.78" stroke) that for some reason had a short-throw crank dropped into it. Are you sure your mechanic measured the throw of that crank correctly?

It appears that you have a 332 crank in numerous possible blocks. The 332 had a 4.00" bore and a 3.30" stroke. The casting numbers for the 332 block were B9AE-B, EDC, 575063 and 5751091. If it is in a 330 block it would be 311 cu. in. If it was in a 391 block it would be a 340. The block could also be a C6ME-A 428 which would be 353 cu. in. Hope this helps but I'm sure it won't. Gotta check the bore to find out the real displacement.

 

I took the crank to the machinest to have it ground. this is when he told me it was a 330. I though that he might have misread the casting #, so I took it home and put the engine togeether, then measured the stroke myself. 3.25'
I was also with him when he micked the bore 4.09 (bored .040)

I believe that the 390 crank and rods just might find it's way into this engine block.

P.S. VIN # indicates truck come with a 360 engine. so someone might have just put in a different crank??

 

Gimme the casting number off of the crank. The 330 and 332 are pretty rare engines so he may be confused. If it was a 330 crank it would definitely be forged steel and have a 3.5" stroke.

 

Well I don't have the crank #'s handy. it is in the truck and I don't really want to tear into it just for the #. however I do remember one thing. the crank flange has a half moon cut-out like a 360. I don't know if any other cranks have this in them. I bought a flywheel for a 352/360/390/ and it bolted right up.


I greatly appriciate all of the help that you guys have given me on this

I was searching for threads on turning a 330 into a 390 or 428 and this is what I came up with.....
I bought an engine that was supposedly a 390(or 391 FT), but after teardown, turns out to be a 330. The crank casting is 2DT-A and the rods C7ME-8. From what I've read, I can still make it a 390 or 428 with a crank and rod change - right? I also read about piston skirt lengths being an issue due to rod angle. Any details would be much appreciated.
I am going to put an RPM intake and Holley 4bbl (650cfm) on and if I have to (if these are ultra low-flow heads) I''ll also get the RPM heads. I was originally thinking about fabbing in a turbo with one of the Ebay Universal T3/T4 Turbo/Intercooler kits that run about $700, but that was when I thought I alread had a 390!
Any input is appreciated!!

 

I really wouldn't put a lot of money into trying to get the 330 to perform. It'll be much cheaper, and better performing to start with a 390.
You can't make a 428 out of a 390, it won't take the +.080" overbore.
The best you could do is make it a 410+ 390 block, 428 crank.

 

There are two different 330 FT engines: 330 2V M/D aka XD (1973/78) & 330 2V H/D.

1973/78 F350's made exclusively for U-Haul have 330 2V M/D aka X/D's.
The 332 FE is a rare engine...today, because it was only installed in 1958/59 Ford Passenger Cars and Edsel's. The 352 also available in these cars.

The 330 2V M/D is the most common FT engine. Millions were installed because it was the standard equipment V8 in 1964/69 B/C/CT/F/N/NT/T500/750 / 1970/78 B/C/CT/F/L/LN/LT500/750.

And...consider how many more were installed in U-Haul F350's.

The 330 2V H/D is less common, but more common than the 361 2V & 391 4V.

1964/67 330 M/D uses the 352 crank, while 1968/78 330 M/D uses the 360 crank.

 

Thanks guys. After more research and your info I'm going to just put it back togther and get a 390 4bbl (I know of 2, but then again, thought this was a 390....) and call it a $330 LESSON ($225 I paid for engine and tranny and $105 for gasket kit....ironic yes).

I did note that these 330 heads have very large exhaust valves and openings though. Maybe I can sell it to some farmer for their grain truck....
