Technical Ford 11 inch clutch

Anyone tried putting a truck 11 inch flywheel and clutch behind a 59AB or Lincoln flathead? Looks like it might fit. Would the pedal effort be reasonable? Clutch should last longer.
Thanks

Usually how long or short a period of time a clutch lasts depends directly on how you treat it.

Usually a "truck" flywheel is going to be a hell of a lot heavier than a car or pickup flywheel on the older rigs so one might give up the potential for quicker acceleration for your potential clutch life.

 

Yes it will fit, they were commonly used in pickups and trucks. Flywheels are all the same size, just drilled different for each size pressure plate.
Pedal effort will be more but not horrible. I have one in my F-1...

 

I strongly recommend NOT using the 11" clutch/flywheel combo. It's SIGNIFICANTLY heavier than the car (10 & 9.5) applications. Will it work? Yes. Pedal effort increases, engine responsiveness decreases due to flywheel effect. There are almost no car applications that 'require' the bigger clutch.

 

Use a 10" if you have a '40's heavy Ford, 9" in something light like a '32. There is absolutely nothing to recommend the 11 in anything other than a truck. Substantial extra weight and effort for what??

 

Thanks guys. The car is a 4000 lb Lincoln Continental with modified V-12, but I now think I can make the stock clutch live.

Hey Abe just replied to this on the zephyr owners club forum.
I am running a french flathead v8 in my 37 zephyr and it still has the original 11" clutch and pressure plate. It connected right up to the original zephyr clutch linkage and pedal ***embly and is absolutely effortless to press down.
I can easily push it down by hand with minimum pressure with two fingers.

4,000 is a lot heavier than anything I was thinking about...I ***umed Ford p***enger. 11 is not all that over the top at that weight, though probably not really necessary. The 4.26 or 4.44 gears also likely make life easier for the clutch.

 

This was a popular conversion back in the '50's for guys who drag raced a lot. It was cheap way to get a stronger clutch for racing.
