A 428 and probably the 410 take a special flywheel.standard or automatic.All the rest of the FE series can interchange Not 428 410. I had a friend back in the 60's that had more 427 than anyone I've ever heard of .He'd buy a Ford 427 short block stick his heads and so on , stuff it in a old Gallaxy drive it for a few months . sell that one and buy a fresh 427.short block.One time he bought a 428 mounted all his old 390-427 stuff on it . He backed it out of the garage .Drove it down the aaley.Backed it back and into the Garage removed the engine.Tried to return it to Ankeny Ford.They would not take it .Mounted it in frame converted into a engine trailer - test stand ,Radiator and all.Tried to scatter the 428 and collect on the warranty. It just threw the belts.Loaned it to a stock car, he blew up the clutch and bell housing.He then sold it to an friend. Later he met that friend while at a bar and was offered that same 428 back Fresh from the machine shop.now.040" over bore.I bought that engine still in plastic bags. I put it in a 63 1/2 Gallaxey I had just bought .That 63 allready had a alltered auto flywheel .It had a 428 with a bad miss. Turned to be a bent valve I traded my engine and cash for the fresh 428 engine. My friend removed the head swapped valve anddrove it for a year. Burnt out that Cruis-o-matic at the strip late summer.Converted the car to C6 .Temporarily mounted trans on a piece of tire tread .I tore part of the mount off the tailshaft housing.While waiting for the tailshaft housing to be welded ,Car out side car jacked up and trans supported (just before Thanks Giving 69 Des Moines Iowa) 28° no
antifreeze.That was the end of that block.A week later I was drafted.After I returned from ait I installed a 65 352 from a wrecked convertable.put my
oil pan and front cover on it. Bought a new C6 352 flywheel from Ford .and built my own crossmember for a 63 C6 combo.oilpan is lower and further to rear. Parrallel Twin 1" square tubing I was quite proud of that cross member.
I ended up buying my original 428 block back before going to Viet Nam.Finished it after returning .got married , Moved to washington ,had kids. I figured Life was over and sold it o a guy in Everett For a jacked up red short bed F 150. Whished I had not done that.
