Which clutch size was standard in SS big block 67 chevelle, 10.5" or 11" ?

it depends what size your flywheel is set up for. it sometimes they have holes for both.

My sources show the 11" clutch as standard on all big blocks. In '67 it was available optionally with all small blocks as an option. The only time I can think of a big block with something other than an 11" clutch was in '69 with the dual disc clutch.
