engines were built by Earl Fabritz during the early C sedan times---he was well known in the wisconsin area---i have 2 complete a12 race prepared engines, 1 good a12 block, 1 good a14 block, 1 complete stock a12 engine and several boxes of new and used parts (note: there are no weber or solex carburetors Earl used modified orig equip carbs with ported manifolds and good clyinder heads)---$750 for all----i also have a 4 speed close ratio transmission---gearset is probably middle-close p/n 32210-27720---$650---please call 503.631.3935

Do you have any cams?

Part Number 32210 -27720 is for the 'Counter Gear', or cluster gear for the factory 'Option 1' four speed.
This cluster is described as having a tooth count of 29t, 26t, 20t, & 16t

This transmission has ratios of
2.862 to 1
1.909 to 1
1.350 to 1
1 to 1

This is the 'close ratio' gearbox while the Option 2 four speed is the 'ultra close ratio' item.

The first gear ratio is roughly halfway between the stock first gear & the option 2's first gear [which is the same as a stock second gear] so this gearbox could survive on the street, but it must be remembered that it is a 56 gearbox [not a 56A] & is best used behind a short stroke crank [up to about 1300cc] in something light [like a B10?] to get the very best from it.

Dman, you are exactly right on the ratios (see club wiki - 56 series transmission).

What is the difference between these:
* 56
* 56A
* 56L
???

I thought that we had this conversation a little while back

The 56 series trans has the ball bearing at the front of the cluster while the 56A used the small, closed end, torrington needle race.
Some of the gears were made a little wider to increase strength too.

I never did figure out if the 'L' was of any particular significance in the 56 series of gearboxes.
'L' for long would be used if there was a shorter version of the extention housing in one of these gearboxes, but as far as I can tell, there was no short version. All of the 3 speed, 4 speed & 5 speed 56 & 56A gearboxes were the same overall length.

There is a wealth of info in This thread, however, it should be regarded as a work in progress & updated occasionally.

The following is a quote from that thread.

The F4W56A is a revised version of the F4W56L mounted on the B110 series. Modifications have been made on the following points to strengthen the gears and bearings, and to improve lubrication performance as well as noise and vibration proof at high-speed driving.

(1) Strengthened gears and bearings: Although there is no change in the gear ratio, each gear has an increased width by 0.039 to 0.079 (1 to 2 mm) and the countershaft, front bearing and main shaft bearing are strengthened.

(2) Improved lubrication performance: To ensure proper lubrication in the rear extension bushing, an oil dam is installed in the center of the extension.

Hmm that sounds familar. I had forgotten... I'm adding that to the Wiki page for 56.

Sounds like some exciting parts are for sale down in Portland.
