I've put a LOT of mid 9 sec passes (800+ hp) at 3800 lbs and a few 8 sec passes (near 1100 hp) on my Moser 60 w/ zero problems. No fancy caps and a regular chrome cover. Normal street gears and nothing cryo treated.
Just took it apart last weekend to change gears from 4.10 to 3.54 and the gearset looks perfect.
