OK, here's the question folks......... I have a 292 Y in my 61 F-100. I have the factory light duty 3 speed trans and column shift. Stock, this had a 10 1/2" clutch. What i found in my truck is a 10 1/2" clutch. However the only available "off the shelf" replacement clutch sets are 12". All the parts stores list this set by application for the 292 Y block. The diaphragm/pressure plate assembly is obviously larger in diameter than stock. So as i am looking at this, i could have the machine shop drill the flywheel accordingly to allow the pressure plate to bolt up. It looks like the starter will clear the pressure plate, and if the pressure plate doesn't interfere with the bell-housing as it spins, it looks like this setup will work. I have searched here, and haven't found anything specifically addressing the bell-housing or starter clearance. IF this works it would be great, as you would have a ton more clamping area over the stock setup. So, Is this possible? Has anyone done this successfully? If so, what mods did you need to do? If this doesn't work, why?
