Technical Y-Block Transmission & diff Choices

I am looking to make something a little different: a 35 ford pickup with a y block engine. I would like to use the stock ch***is but wonder about transmission choice and differential. I would like to have an overdrive and would be interested in what some of the "preferred" choices might be. Would a 3 +1 (Granada) transmission fit in well or should I consider a BW older style out of a 60's ford? How about a T5? Finally has someone out there set up an AOD with this engine in this type of ch***is?

If I would be running with 15 inch radials what would likely be the right 9" rear width for this kind of set up?

Thanks--Pete

PS--Your help made that Model A possible. Thank you!

 

I'm planing an A coupe with a Y block in it. I have '64 F-100 as a doner, was going to use it all, 3sp and 9 inch. I watch this just to see...

 

My y block came from a 64 f100. It came with a factory 4 speed and a 9in. It's geared for about 55 mph. I'd like to upgrade the rearend gears and ****** too so I'll keep an eye on this thread

 

I used a 9" out of a 66 or so F100 on my 1935 Ford pickup. Its too wide so I cut each rear fender down the middle and added a 2" wide strip of metal. Fits good, looks good now.
Any 9" differential will fit so you can use any gear ratio you want.

I too want to know which overdrive will work on a Y block
I used an 84-87 F150 fully synchronised 3 speed with overdrive on my Model A engine but dont know if it will work on a Y block

 

Building a 31A now with the following formula; 292, flat-o-matic adaptor, c-4, 9" with 3:50 gears, 31" tall rubber. Not an OD trans as you asked about but calcs out to about 2600 rpm at 70 mph (fwiw).

 

Remember this was the OP question.

 

am currently running a t-5 in my 32y/block,easy install with mummerts adaptor plate,mustang clutch disc,1/4 in.off mainshaft and new revised pilot bearing.have also installed a aod in my chopped 54merc 292 tri carb. more expensive benstein(?) kit, but worked to perfection. follow your heart.....after all, isn't this what this hobby is all about?

 

While I didn't do something as involved as what's been posted here I did install a T5 in my 57 Ford. Running a 292 w/3x2's & 3:50 rear end. With the 3sp @70 it would run 3k rpm's down the highway. With the T5 it runs around 2200. Only beef with it is 1st gear runs out pretty quick.

 

I had the 86 f-150 3+1OD in my '35 w/flathead. Gear ratio's too wide for the flattie, may be OK with the Y in your truck. Went to t-5, all is good now. Putting a y-block in a'29 coupester w/t-5 and 8", 3.55 gears, same as in '35. Y-block is quite a bit longer than flattie, so be prepared for firewall setback.

 

are you saying you used two adapters?

 

Which T5 are you using?

 

Hi 1929 coupe 60 ish 292 Borg Warner T85 w/r R10 OD 1941 ? Banjo pickup rear end converted to open.
1900 rpm @60mph Happy.

I setup the OD on a mech lever and solenoid in a switch works great

 

First-generation Ford Bronco 9". 3.50:1 gears were common, and would work fine with a T5. 58" wide, wms-to-wms, 5-on-5-1/2" bolt pattern.

 

I used a mustang t-5, mummert's adapter and an s-10 tailshaft housing to move shifter forward.
