    It would be better if you had a little more but as long as you have free play on the pedal you will be ok. Unlike a mechanical one which will be pulled off the clutch fingers they will always touch/ride the clutch fingers. Heating up the disc may take up the .030” but I’d still try it. The block plate will make perfect.
    Proper bleeding helps. We just stick the bleed hose in a cup of brake fluid and pump the pedal a few times and close the bleeder.
    Keep a look out for leaks if it’s not new. Good luck.

    I'm too tired to contemplate this right now, but doesn't this clearance decrease when the clutch disc wears? Also, if for drag racing, don't rules require the blow-shield front plate? (Sad story -- I just missed a Chevy blow-shield/bell housing with front plate at a local swap meet, due to slow decision making, for $25!)

    Yes, as the disc wears the fingers are moved closer to the TO bearing. Hydraulic ones are not like mechanical like I said. They sit on the fingers most of the time. Don’t know how your system is but pedal free play will by you some time. I’ve used Rams, McCleods and Howe’s and some without plates. Are you sure you squeezed all the fluid out? Do Speedways have a finger to stop them from turning?
