Corvair FC Drive Line

[Misha]

I am building the Corvair FC based on the Hurst Hemi Under Glass and am perplexed by the drive line to the rear end. I have replaced the kit engine with BBC and am keeping the rest of the drive line. On the engine plate is what appears to be a clutch, yet what happens next is a mystery to me. Is it a direct drive or an “in and out” box, similar to the CAE found on track cars?

I’m currently making the clutch bearing fork to be activated by a hydraulic slave cylinder and wondering if an gear box would be activated by a solenoid?

Any help or photos would be great! Thanks Misha

The AMT HUG kit is largely based on the '65 funny car of Tom McEwen et al. I think there were some articles written about it at the time, you might try googling to see if you can find any details online. Good luck!

For what it's worth, that doesn't look like any kind of gearbox to me.

A 2-speed planetary box could fit in that general volume, but it would be shaped differently (it would look like one section of a Lenco).

Likewise any in-out box I've ever seen...but I'm sure there's a lot of stuff I've never seen.

What it does look like is an adapter plate / flywheel housing bolted to an engine plate, with a housing for a multi-plate clutch bolted to the adapter.

The flange on the clutch housing where a gearbox would mount appears to have a plate bolted to it in turn, configured as an output shaft bearing support.

A torque-converter could also fit inside that general volume, in which case you'd still have a single-speed driveline, but with some built-in slip.

Again, the assembly doesn't really look like anything I'm familiar with, but that's not at all definitive. And again, there's lots of stuff I haven't seen.

On the other hand, it certainly wouldn't be the first time a kit designer included incorrectly rendered mechanical bits he didn't understand the function of.

If it IS supposed to be simply a multi-plate clutch setup, your clutch arm seems reasonable for a model.

Clutch-only drivetrains weren't uncommon on high-horsepower drag cars.

It's important to know when the model was tooled as well (or the kit it was derived from), as that will have a direct bearing on the tech that's represented.

Thanks Bill & Ace. I agree that the setup is unique and most probably based on fiction. I believe that I will go ahead and consider it as a multi-plate clutch assembly only. 
Thanks again, Misha

I ran into this same question on my build. The answer can be found in researching "Casale V- drive" found in the "Hemi-under-glass"
