I have a 93 blazer with the 350 TBI and 4l60e transmission. I am wondering if anyone has swapped the 454 tbi and 4l80e tranny into their blazer. I have no issues with doing the swap other than what I need to do with the Ecu. I would like to keep the fuel injection but if I cant find info on this ill just go carb and buy the tranny controller. I am sure somebody has put a 454 in there TBI blazer somewhere.
