My build is very similar to yours but I'm not as far along as you yet (still accumulating parts). 95 k2500, 4l80e, 4:10 gears, building a 355. Already have vortec heads and a roller cam with slightly less duration than yours. Have a 46 mm bored tb from tbiparts.com and have been considering 65lb injectors. If your gonna stick with the 80lb in yours and you would be interested in selling your 65lb, pm me, I may be interested. I will be following your build with interest!
