Clutch size
Do all Oldsmobile Cutlasses with a manual transmission have the same size clutch?
I have a 77 442 with a 260/T-50 combo and plan to put a 455 in place of the 260. I've looked on line and see that 10.5 and 11' clutches are available but seem to interchange between the two.
Can somebody give me the scoop on which clutch goes to what?
Thanks.

SBOs used 10.5", BBOs used 11". The flywheels should be drilled for both (well, they were so long as the BBO was being made). And yes, the W37 is the exception to this.
The question is irrelevant if you plan to put the T50 behind a 455, however. That trans won't make it to the end of the driveway.
