Hello
I need a good 10in flywheel for my 40 ford it has the original engine in it as assembled from factory...I was going to replace the clutch. The engine is in the car.I understand there are several types. Can I please get some feedback please.

Normally it would be 9".

Original 40 Ford would not have originally had a 10-inch. (As flatjack9 has said)
'Course, you didn't say if it's a 40 truck... that might make a difference.
So, I assume you are looking for a 46-48 flywheel (car) which would normally be 10-inch. Or, as flathack9 posted, a 9-inch from 40 and earlier.
For whatever it's worth (and I'm only offering, not placing an ad), I have an unused 46-48, 10-inch flywheel and fresh clutch, from a project that I abandoned. Flywheel has been surfaced and balanced. All work done by Clutch Masters, Rialto, CA.
And, I also have a 40 (and earlier) flywheel for 9-inch. This one is 'as was', not resurfaced or balanced.

Another thing to keep in mind is the flywheel can't be removed without removing the oil pan, unless you have the truck two piece oil pan on your motor, or if you have an 8ba with the removable bellhousing. The 9" clutch as was said was stock on a 40 motor and works just fine. So, before you buy anything make sure you are Ok with the extra work involved to change the flywheel. Removing the oil pan on a 40 motor while it is in the car can be done but would be easier with the motor removed.
