Will a 59AB engine with a 11" clutch bolt up to a 40 to 48 side loader transmission or will there be clearance problems?

I am pretty sure there will be clearance problems. Maybe the 10 in. clutch would work.
I have a gut feeling that the stock pressure plate, clutch and flywheel is the way to literally "go". An 11 inch clutch is overkill. Why do you want to use one? What are you building?

The 11-inch Long type was generally used with the 4-speed but should work on the light duty 3-speed whether it is the top load or side load version from late 1937 on up. It is a big heavy thing though and you will lose rpm build performance due to that. I would use the 9 or 10-inch Long types myself.

I am building a spare engine for my '48 car. Granted, an 11" clutch is probably overkill, but that's what I have on hand. Also, I might end up using this engine in a 1 1/2 ton truck.

I have an 11 inch clutch in my 50 with a WC T-5 (93 Mustang trans). Full race flathead 286 CI. Love it along with the 8 inch rear end out of a Maverick. No more blown OD transmissions or slipping clutches. Yes, I drive it hard.
