460 flywheel problem
i can always use my 429 cast iron bellhousing (heavy!)..the 67 top loader is going to be rebuilt with the big block parts. i am using a 390 flywheel 184 tooth (it takes the 11" clutch) use the hydraulics from the 85 setup. and try the 460 starter..which looks like according to turbo i will need some more engine/bell plates..as i dont have a garage and the car is under tarps in the driveway (under snow) i will have to wait till spring to assemble/try..thanks again to all who have helped..

460 flywheel problem
ok its getting really poor here...(wallet and progress)...the first kit i bought was a the 12" 460 clutch kit. It wont fit(too big across) for the 390 style flywheel (184 tooth) ...so i emailed the seller of the flywheel and asked if any Ford 11" will fit even if its for a small block..he emails back and says mfg says "any 11"...so i buy on ebay another clutch kit..11"(Ford 11" Clutch Kit 1977-82 Pickup, F Series Bronco)...guess what?..it dont fit either! 
This clutch pressure plate has evenly spaced holes at 6 3/16 on ctr... the flywheel has three sets of holes, each set is 3 7/16" from the ctr of one hole to the ctr of the next. From one set to the next set is 8 9/16" on ctrs... Does anyone know what pressure plate will fit this?

460 flywheel problem
maybe i should clarify a bit here too..the flywheel is not a stock 390...i assume it is a 390 STYLE flywheel because it has the same number of teeth as the 390 did(184)..so...with that in mind and the dimensions i gave i hope that someone can let me know what pressure plate will fit this thing...oh and i did contact the seller again to ask the same question...so somebody help?

352/360 flywheel = C5AZ-6375-K / Marked: C5AE-6380-J / 184 teeth / (6) 5/16" -18 pressure plate attaching holes on a 12 3/8" bolt circle / 11" clutch.

ok thanks with those dimensions it is clear that this is an aftermarket flywheel for a 360...as the boltcircle dims and the teeth number match along with the clutch plate size...thanks...

Hey guy's I am kind of new to this site but I do know this if you put any flywheel on a 460 other than a 460 flywheel it will shake your teeth out.

460 flywheel problem
it will only shake if you mismatch the internal balanced and the external balanced engine parts. pre78 are internally balanced after that they had the balance external..so an internal flywheel will not work on an externally balanced engine, and vice versa....

The same A/T flexplate used on 429's was also used on 460's 1968/thru midyear 1979: D1SZ-6375-A
The 429 manual trans flywheel (from the cars) was used on 100's of 460's converted to manual transmissions prior to 1983.
I sold dozens of those 429 flywheels back then, and haven't heard a complaint yet.
1983 was the first year for a 460 with a manual transmission.
What one has to be careful of is the difference of 1979 460 engines.
D1VE-6015-AB is the bare block casting number for 1971 thru midyear 1979 429/460 engines. It uses a harmonic balancer with a non weighted spacer.
D9TE-6015-AB is the bare block casting number for 460 engines used from midyear 1979 and later. It uses a harmonic balancer with a weighted spacer.
If the balancer/spacer doesn't match, YOU WILL have a vibration!

Bill, Do you worry that once you get old and gray and the old brain starts to slip that you'll be sitting around in a rocker slapping yourself on the head saying "axle 4234, oil filter 6731, drain plug 6730, switch 11450, bumper 17906 no 17757 no 17k835" and so on.......Those basic numbers just seem to stick. I was in parts for 13 years until 2004 and still can't get those number out of my head. Reading your posts brings back fond memories. Phil

460 flywheel problem
i just had a thought..i have seen input shafts and clutch plates advertised as having 1 1/16" or 1 1/8" dia input splines. if i rebuild the top loader to big block specs,will the input shaft be larger in diameter than the small block version,(1 1/8 versus 1 1/16")therefore requiring a larger dia spline on the clutch plate? if this is so, then there may not be a 11" clutch plate with a larger dia spline, or is there such an animal????

Grey too, but at least I still have all my hair.
Waiting on ppl at parts counter for 35+ years, and now here on FTE will turn anyone's hair grey.
A parts man has to be part dentist, cuz you gotta pull the info from ppl.
What year is it? What engine size? What model?
WHAT..what..what? The ppl must think we're mindreaders.
LIFE OF A PARTSMAN
I work behind the parts counter, in a Ford dealers store.
Sometime's I'm called a genius, sometimes I'm called much more.
I'm supposed to know the numbers of bolts, nuts and gears...
...For every Ford that was ever made for more than 60 years.
But...life would be much easier...and I'd grin from ear to ear...
...If the customer would only tell me...the make, model and year.
