FE series engine mount
I'm looking at purchasing an original Ford 428 engine from a 1966 Thunderbird to put in my 1966 F250 4x4. The 1966 F250 4x4 has a 3 point engine mounting system. Does anyone know if the Ford Thunderbird 428 engine could be mounted in the three point system in the 1966 Ford F250 4x4 without any modification? Any help would be appreciated. Thanks!

You cannot use a 352/360 or 390 flywheel or flexplate with a 428, as a vibration will result that eventually will tear the center from the flywheel/flexplate.
1966/67 428 uses the same harmonic balancer as 1961/67 352 and 390 but...the 428's flexplate and flywheel are different.
Since all Thunderbirds with 428's came with C6's, you will need to find a 428 flywheel from a 1966/67 Galaxie/LTD: C6AZ-6375-A .. marked C6AE-6380-A
1968/70 360/390 & 428 use a different harmonic balancer, but the flexplate and flywheel are specific to the 428 only.
1969/70 428 Super Cobra Jet uses a different harmonic balancer.
And btw: 1966/67 Thunderbird: 390 was standard equipment, 428 was optional.
So you better make damn sure it is a 428 by measuring the stroke: 390: 3.78" / 428: 3.98."

I have seen a 428 in a truck with a 352/360/390 flywheel. It did vibrate really bad, but I highly doubt that the center of the flywheel would break.

Thanks guys! Really great information y'all provided. One more question. If I bored / stroked the original 352 engine to 428 cubic inches would all the original 352 components work such as the flywheel, distributor, oil pump, ect.? Thanks again!

Finding a block that will bore out that far aint gonna be easy, #1.
#2 if you put the 428 crank in the 428 flywheel is required to match the crank balance.
I have read of machine shops changing the balance on the 428 crank and it all goes out the window.

If you had worked at a garage or a FoMoCo dealership, you would have seen this occur.
And today...this is even more common, cuz people love to swap parts and some of them haven't a single clue.
They install the wrong flywheel or flexplate, or the wrong harmonic balancer, then wonder what's causing the vibration...that will eventually tear the center from the flywheel/flexplate!
Coupla years ago, I read a thread where a guy had pulled a 302/C4 from a 1981 F100, then installed it in a 1965 F100. He also bought a new 302 flexplate.
He then showed up here on FTE and wondered why there was a vibration and why the 302 had no "get up and go."
Mr. Clueless was unaware that some 1981/82 F100's came with the anemic smogged up turd 255 that uses a different flexplate than the 302.

C5AZ-6375-K .. 352/360 Flywheel-184T ring gear-Use with 11" clutch / (6) 5/16" -18 pressure plate attaching holes on a 12 3/8" bolt circle.
C5AZ-6375-L .. 390 Flywheel-184T ring gear-Use with 11 1/2" clutch / (6) 5/16" -18 pressure plate attaching holes on a 12 7/8" bolt circle.
C6AZ-6375-A .. 428 Flywheel (except CJ & S/CJ)-184T ring gear-Use with 11 1/2" clutch / (6) 5/16" -18 pressure plate attaching holes on a 12 7/8" bolt circle.
352/360/390/428: Same throwout bearing and pilot bearing (1 27/32" O.D. x 43/64" I.D.)
390/428 (except S/CJ): same clutch disc and pressure plate.
But the 428 flywheel is 428 ONLY. The 428 flexplate is the same as Merc 410, but it's not the same as 352/360/390.
The above pertains to 1965/76 only. 1958/64 FE engines use different flywheels and related parts.

I just sent my stock flywheel to the machine shop with the motor to have it balanced when I did my 416 (410).
