351m clutch parts for 460 swap
Hello! Sorry to bother you, but I'm putting a close ratio toploader from a big block torino in my 84 f150 2wd. My plans are mechanical clutch. I have bought the mcleod 1-3/8 input shaft clutch fork and throughout bearing. A internally balanced 390 flywheel and got a d9ta-7505 bell housing from a 351m truck. I'm using a 77 460 engine in it. But what are te proper part numbers for the clutch equalizer an pivots that I'm going to need for that bell housing???? I want to use all the 80s mechanical pedals so it looks factory. Will the 79 bellhousing work with 80s clutch setup??

I think you have bigger problems than the equalizer bar, etc. When I put a 460's transmission behind a 351M I learned that the flywheel on a 460 sits 1/2" further aft of the back of the block than does the flywheel on an M. So, is the transmission you are using from behind a 400 or 460? That will determine the input shaft length. And then using an M bell housing may cause a problem as I think they are shorter than a 460's bell housing due to the flywheel position.
You may already have that all figured out, but if not it is something to be thought through.

You would think I'd know that since it was my era, although I was a Mopar guy at the time. But, my limited understanding of the 385 series is that the difference in the two is stroke so that won't change the block-to-flywheel measurement. Right?
So that still leaves us with a 460 engine and a tranny that should have the proper input shaft length for that engine, but an M bell housing that may be of a different length than a 385's bell housing. I would want to verify the bell housing length before going further. Then, if that's ok we can explore the equalizer shaft and the associated parts.

The block and its crank flange 'stickout' are the same, just the stroke changed between U and Y cranks.
There were no gearboxes fitted behind a 460 in trucks until 1983 and hydraulic clutches.
I would think a clutch for the Torino will fit.
I do not know for sure the depth of the Torino bell, but it would have been mechanical.

At one time, there was a special spacer available to fit between a 460 block and 400 bellhousing, due to this extra crank flange "stickout". It allowed for converting a 460 truck to manual trans, or swapping a 460 in place of a 400. Obviously, the trans had to be set back an equal amount, which most driveshafts would allow.
I dunno who offered it, or if it still exists. I just remember seeing something about it way back when.......
A good fabricator could easily make their own, though. The starter would most likely need to bolt directly to the bellhousing, rather than to the spacer, for proper engagement.

well the plan is to use the 390 flywheel i got. Its from exeddy..its part number is fwfm113. its thinner than the 460 flywheel. the bellhousing i have is 6-1/4 deep. same as a 429 bellhousing. the late 80s 460 bellhousing are 6-3/4 i believe. the clutch im using is for a 1-3/8 shaft toploader. 11'' centerforce. so just needing to know about the zbar and equalizers

If he has an internal balance 460 I think he will be fine with the M bellhousing and the 390 flywheel.
As for the cutch z bar and pivots, I believe the bellhousing side will work with both a BB and a SB bellhousing, provided it is the type that has a bracket that bolts on with 2 of the bellhousing bolts. The z bar is the same on all, as is the frame side pivot.
I have no part numbers for you unfortunately.

internal-external... the crank stickout didn't change.
The reason for using a 390 flywheel is less depth (don't know how this affects starter engagement) and neutral balance.
I would call Centerforce and ask if that clutch will clear in this application.
I am SURE they have seen this before.
The Hi-Po parts CD has all the diagrams and part numbers.
I just don't have anything with an optical drive.
