Yup, same experience here. Nice to see another 427ci 03Z running the Mantic 9000. I've had mine for almost a year now and it's still going strong, best aftermarket clutch I've ever used. 
Nice to see other shops besides just ECS starting to realize how great this clutch is. I bet in a year or two most high HP street driven Vettes will be running one of these.

I've got around 1500 miles on mine, with 400 of those before I killed 2nd gear blocker or synchro.. In those 400 miles I went to the track twice and it did just fine.. My 2nd gear problem was already there and finally bit the dust on my last pass.. I've never had any problems with the clutch what so ever, but the 20 lbs in moi I lost from the monster to this killed me.. With my cars power band and having 3.42 gears.. I'm putting a replacement monster back in it when I fix the transmission.. My car with a 25.5" tall tire still bogs down a bit on shifts from going under my power band.. It was horrible with the 27.5" tall tires.. I will also say cam surge is way worse with the lighter mantic.. I'd imagine most of the FI cars won't have any problems cause they're cars are not near as rpm sensitive as my car is and it's not a lack of power being my car NA makes 660/570 but it's just to light for my setup.. If anyone is looking to save a few bucks it'll be out of the car and for sale in September..
