Tom turned us on to this trick he says is a must-do. He uses powdered "Quick Seat" dry film lubricant in his bores. No other lubricant is used in the bore, and the film is applied to the dry, clean surface. He claims this Total Seal product, while expensive, can be used conservatively and delivers excellent results. Ring seal is ultra-critical in performance engines, especially for a dyno entry like this. We've not used this product before, but after hearing Tom rave about it, we'll have to try it in the future.
