Need clutch suggestions- 340/4-speed, Street/Strip

Well, I'm getting ready to put the 340/4-speed in the Swinger. I'm looking for a good street/strip clutch disc, 10.5" in size. The flywheel and diaphragm pressure plate are fine. I just need a new disc. Motor is a 340, hopped up to ~350-400HP (no real #'s yet). I'll be running a hydraulic pull-style clutch set-up.
Any opinions would be much appreciated.
Thanks.
