I've got a pair of mis-matched FT heads and I'm trying to figure out what they are. First off, the truck is a real hodge-podge, at some point it was a 1962 F600, now it's all kinds of years mashed into one. It's got a 330 MD (small crank snout) in it and a clark 5spd.

The first head does not have thermactor bosses in the exhaust and as best as I can tell the engineering number is missing the first two digits, __TE-6090-E. At some point someone stamped in a 7, so I'm assuming that would make them a C7TE-6090-E. But! It looks like an older head and I can't find any reference to one with that part number. I did find reference to a C4TE-6090-E.

The second head has the thermactor bosses in the exhaust and the engineering number is barely legible, but as best as I can tell it's a C7TE-C, possibly a C7TE-D.

Does anyone have any specs on these heads? Chamber CC, valve size, etc? Are these 330 heads or are they off a 361 or 391?

Any help is much appreciated!

You know Sam.. I have a whole motor waiting for you.. 330 HD...
and a smokin deal just for you if you want it... I have no need for it.. make me an offer I cant refuse

 

Uh oh! What's the casting number on the heads?

If it's got the small valve stems I might have to figure out a way to shoe-horn it into my garage!

Sam

 

Lets horsetrade..
I need a light duty 300 clutch bellhousing and associated parts... (for an f250 project)

You need my hd motor

Ill see if I can read the casting numbers..Ive never looked for them..

 

I just asked a guy I know to chime in here, not sure he's still visiting FTE or not, but it's worth a shot.

He has some intimate knowledge of the 60's FT's and the surrounding vehicles

 

Thanks Krewat!

Cam- I'll send you an e-mail, I just might be able to fix you up

FT engines introduced in 1964, used thru 1978.

T/E (Thermactor Emission-smog pump) introduced in 1966, but 500 series and larger series trucks with 330's (M/D & H/D) didn't have T/E until 1971.

If you find a T/E head w/a C6TE, C7TE or C8TE casting number prefix, it's an FE head.

1966/67 and some 1968 F100's sold new in CA have T/E, dunno about other states.

 

Thanks Bill, maybe it's a D7TE-C? That would explain the T/E bosses.

Is there any way to look up which castings use which size of exhaust valve stems? There was the 330 MD that used regular FE sized stems and the HD motors used bigger ones.

If you have a small crank FT it can be one of several variations. What exhaust manifold are used on this engine? If they are similar to pickup style with no center exhaust port, they are the same as pickup or car heads. If they have the center port they are FT heads. A 330 MD FT with small crank nose uses the same crank as a FE and the distributor is the small diameter type. Also the small nose uses the same balence as a FE as far as flywheels go -- neutral balence. I seen 330MDFT's with both types of timing covers and water pumps. One style is the same as earlier pickups with the front engine mount and FE style water pump. The other style uses a timing cover similer to the HD engines with front mount and 429 style water pump.
All HD style engines are big crank snout with FT style heads and manifolds . The HD's take different flywheels as they are balenced differently, HD's use a different distributor because of the larger oil pump drive. FT blocks can be used for FE use with a bushing in the oil pump drive hole. FE heads and manifolds can be used on FT's

Thanks! This one is an MD for sure, it's got the small dizzy, small crank snout and FE style waterpump. It's got FT heads on it, they've got the center heat crossover.

330 2V M/D FT use the same crank as 352/360 FE's, but the flywheel and harmonic balancers are FT only as are the cylinder heads.

330 2V's have either a 12" or 13" clutch, the two flywheels are 330 2V M/D only. 330 2V H/D, 361 2V & 391 4V use a different flywheel.

1965/76 FE: There are two different flywheels. 352/360's have an 11" clutch, (6) 5/16" -18 pressure plate attaching holes on a 12 3/8" bolt circle.

390's have an 11 1/2" clutch, (6) 5/16" -18 pressure plate attaching holes on a 12 7/8" bolt circle.

Even thought the FE (1965/76) & FT (1964/78) flywheel ring gears have the same number of teeth (188), FE's uses a different ring gear than FT's.

 

I understand what your books tell you , but there are lots of half breed combinations out there. I've seen and built many half breeds so the customer has a running truck. I've also took a 330MD and put FE heads on it and put it in a Merc Station wagon. I've also put a 391 in a 74 F250, was'nt fast but made a heck of a tow vehicle. I've put car motors in F-5/6/7's, not the best idea but you do what you must. My 57F700 wrecker has a 67 390 out of a GT Fairlane . so just because the books says it does'nt work does'nt mean you can't do it.

Thanks Bill and Hotwrench!

Bill, what is the part number (if there is one) listed for the 330 MD heads?

Hotwrench, I've got all the parts to build a 410 short block, my plan is to top it off with some 330 MD heads and really build some torque! I'd use 330HD/361/391 heads but those sodium filled 7/16ths exhaust valves are expensive.

Sam

 

1964/72 330 2V M/D: C4TZ-6049-D .. Cylinder Head.

HOTWRENCH: I didn't say FT's wouldn't work in other applications, I only listed what was "as original."

1948/51 F7/F8's came with the 337 flatty V8, a slightly different version was installed in 1949/51 Lincoln's & Lincoln Cosmopolitians.

These cars came with 3 speeds, overdrive was an option. Hydra-Matic was an option in 1950/51's, so I wouldn't be surprised if there's an F7/F8 out there with the Hydro.

 

Thanks Bill, are there any later numbers? I'm still trying to figure out what the real casting number is on the head with thermactor, it's got me scratching my head. It's got the center exhaust crossover so it's an FT for sure, but the combustion chambers are very different from the C4TZ-D head and its got 3/8 valves. From what I understand all the HD motors got the sodium filled 7/16ths valves. Maybe it's a late 70's 330 MD head?
