James 1968 C10 6.0 6l80 Swap

James installed a 2010 LY6 6.0 and 6l80 into his C10 last summer and brought it to FLP and myself for finishing. This year he brought it back for a BTR Stage 2 PDS cam(227/242 .614/.592 122+6) and accompanying tuning to go with his 4.10 Trailblazer SS differential. 4.10 gears and a 6l80 make the first gears just about useless as you go sideways with the tires up in smoke.
