Transmission / Overdrive: 1963 Lark Gearbox swap opinion

[Rapps]

What would be a common swap from a Power flight auto over to 4 speed manual I am running a 289 Packard and the Danna diff

The 289 should be Studebaker. T10s were the 4 Spds that were stock. Several individuals have installed t5s, tkos etc. In any case, you would need the manual "ford" pattern bell housing as well as flywheel, clutch and clutch linkage and if course a shifter for the t10. If you go the t5, tko, or other you would need the adapters for the stock manual bell housing.
I am happy with my Avanti R1, T10 and 3.54 Dana tt.

Once the transmission selection has been determined, the clutch linkage is a crucial decision. Your Lark should have the suspended pedals, so it's possible to use the OEM Lark manual clutch linkage, but unfortunately, it's a flawed design. on all my recent conversions, I've used a hydraulic clutch master cylinder and hydraulic throwout bearing.

Actually, the "P" denotes president which is 289 either 2 or 4bbl. 259 were "V" engines except in 55 when they were "P". I believe Packard engines were "L" or "LS" if supercharged.

There you go Thanks

It probably makes sense just to rebuild the auto and source the correct floor change and linkage. I think they are a great combination

Agree. Once one becomes accustomed to pulling the floor lever to L, manually shifting to second and then third, the Powershift works really well with the Stude V8.

I have a 61 Hawk 4 spd that last year experienced a xmission failure. Instead of rebuilding the T-4 I replaced it with a bolt in Mustang T-5. I used a 1994 World Class WCTS. WC means it can handle an extra 50hp. The case holes lined up to the bell housing. Other work had to be done. I have drafted a memo I was going to share with the forum but have not done it yet. I can post it if you think it will be of help. The 5 spd makes the car drive a lot better and smoother, especially with the dana rear end.

[Rapps]

Why not post it. I am sure it will benefit

If your hawk was Stock, I am pretty sure you had a Borg Warner T-10 4 Speed!

Not a "Bolt-in", if you Modify the T-5 Front Bearing Support, Input Shaft, Driveshaft Yoke, and Clutch Linkage.
