Girdle

Ironmike. The use of a girdle I feel would only be needed in a unit that you are pushing the blocks capability to the limit. In my case, the circle track stuff we make that sees 14 to 1, 7800rpm for 5 minutes and the part that hurts the worst.. how do you start the thing on a cold race day? Raw fuel down its throat! One backfire and look out. This to me is where and when a girdle could or should be used. A hot street motor shouldn't see the need to be girdled. Definitely use studs or billet caps and studs (next level of strength) and you'll have as strong of a motor as needed.
