If you're thinking of running the '21 flywheel with the 010 card you have, then I think it'll go pop of sure. Matt's your man for this type of stuff. I've been running the 300 with a '21 flywheel to give it a little more advance, but think i'll only give about 3-5 more gee-gees. Well that's what he told me.
