LS3-Based 418ci Engine Build - Big Power, Small Budget
GM LS3 main caps are torqued to spec in order to maintain load conditions on the block before machining operations begin. The block is then set up on a Rottler F-67A three-axis CNC machine by Heber Ramirez of Sunset Racecraft to both deck and bore it. The deck height is measured to determine how much machining is necessary to ensure a flat deck. According to Ramirez, "A production LS3 block has a stated deck height of 9.240 inches, and traditionally we see 0.003-0.005 of variability across the deck surface." In this case, the variability was quite low, so a total of three passes were taken at 0.001 per pass, and the deck height was set to 9.238 inches. View Related Article
