410 Fly Wheel
Ok If I Understand Correctly From All I Read On Here I Can Order A Flywheel For A 428 That Was 4 Speed Manual? I Have Been Trying To Find A Flywheel And No Luck Err!!!!!!! Any Clue Where To Get Such A Thing Would Be Helpful.

410 flywheels
F250Mike, the 410 takes the same flywheel as the 428. All of the 410s were external balance, Bear is mistaken on this one. Any one who sells flywheels or flexplates should be able to get you one. The 410s were offered in Merc's in 1966 and '67. 428s, IIRC were offerd 68-70. Don't let anyone tell you the that the 410/428 'wheel is rare or special or has to cost twice as much. The only differance is the balance. If you can't find one at a good price ready made, you can start with a normal zero balance 360/390 'wheel and have the imbalance you need added at the balance shop. It really isn't that big of a deal. You can weld extra weight on where you need it, or you can drill on the opposite side. DinosaurFan, on work's old 'puter

Try Jegs/Summit. Most of the aftermarket FE flywheels include a bolt on weight for the 410/428 applications.

flexplates and flywheels
Bear, just when and where is it that Ford says that the Merc 410 was internal balance ? You are the one, and the only, person I know who believes that to be the case. I am going from memory and from Steve Christ's rebuild your FE & FT book. If you don't have a copy, I think motorhaven has them for sale on this site. Or from Amazon, less than 20$ either way.

A lot of books have misprints.
From my research, the 390 block and interns is the same as a 410. Difference is the 428 crank and shorter connecting rods 6.490". You can reuse anything else in the 390. Including your flywheel, be it any FE flywheel (360/390/410/428), as long as you extenal balance it.

flywheels
F250, you might look at flywheels from McLeod. Or any of the clutch companies should be able to help you out. But you will have to look at car flywheels, cause the 428 didn't come in a truck. DinosaurFan, on work's old 'puter
