6l80e to 4l80 conversion on a 2009 GMC Yukon XL Denali with 6.2
Hello all, I'm new here. Currently I'm in the process of making a few changes to my Denall. First and foremost I want to install a monster 4l80e rated for 1100hp from the current stock 6l80e transmission. Then there will be significant changes to the l9h 6.2l engine, starting with LS3 heads, next BTR stage 2 V2 truck cam, headers, borla exhaust and last but not least a pro charger supercharger. My questions are..... What will it take to do the conversion on transmission and is there a way to run timing gears on an EFI engine.?
