first off, my name is ray and i'm building a 84 4x4 with a granny 4. i just got an m motor that was an automatic. i know i need a 460/429 style bell for it, just got one on ebay. what i need to know is if a windsor flywheel and clutch will fit it. any help would be great

 

I doubt it will, but to make sure, look up a 81 truck with a 351m or 400, and see what the part number is for the flywheel. Then look up a later truck(85 would surely work) with a 351w or 302(whichever type flywheel you have) and see if it's the same part number. The name of the game at these stores is adjusting and keeping the inventory at each store and warehouse to a minimum, so if the part is the same, they will only keep one on the shelf and interchange it with as many models it will fit. Make sure you plug in the proper year 302 flywheel you have, since they changed it around 82.

Places to look are autozone'a site, rockauto's site, Napa, etc.

 

Will not fit.

 

Welcome to the forum floridaray!

Granny4???
T-18? ... T-19(460 4x4 version with the 6.32:1 first gear?) New Process?

Like Critter said, the Windsor flywheel will not fit.

And the 460 bellhousing being deeper is going to cause input shaft engagement depth issues.

Gary Lewis has a thread going where He is putting a ZF5 behind his father's 'M' and he has a lot of information you might use about running a 460 bell behind a 351M/400.
(even though you don't need to deal with the disc needing larger splines)

Oh, boy.... I expect Gary to respond to this...

 

I expect no less than 8 pages!

 

Micro-analysis time.

 

If you have a mechanical clutch start hunting for '78/'79 pickups with an "M", grab the flywheel and bell from one of those as it should work fine as well.
