Thread: Clutch size question

Tweet

Well the weather seems to finally have broken and I plan to start assembling the parts I have collected over the winter. I have one naggin dlillemma. I picked up a bellhousing that the owner claims is good for a 10.5" or 11" clutch. My 454 wrecker motor came with a 12" disc. I plan on using a 15530202 bell from an 85 pickup truck. What are my options?

1) Can I use my 12" clutch set up in my bell? Simply picking up a fresh clutch / press-plate and have my flywheel turned...

2) Go with a 11" clutch / press-plate set up...and possibly need to purchase a smaller flywheel to accomodate the smaller press-plate.

I do not know if an 11" pressure plate will bolt onto a flywheel from a 12" setup. I do not have any old parts around for mock up, and my motor is currently bolted onto a stand which also makes it impossible to mock up.

Anyone ever been in this scenario? Any input would greatly be appreciated. Or does anyone have an old 10.5" or 11" pressure plate laying around that they could measure the bolt holes for me?
thx Joe
