We are the only company in the world utilizing our proprietary block prep service prior to machining the block. This in-house developed service allows us to run a factory bore size and not cheat by using a smaller OD sleeve and a tiny piston. This results in engines that are more powerful with factory displacement over the competition. Our service removes the risk of the vapor ports between the bores cracking behind the sleeves and leaking coolant down into the crankcase. Below is a picture of a block that did not have our block prep service. We removed the sleeves to find cracked coolant passages between the bores and visible signs of coolant entering the crankcase.
