i screwed up in my typing i meant to write electronic pedal but for some reason wrote efi maybe i need more sleep. i was told by 2 or so different people that i could get a 5.3 with the harnesses and pcm etc and then buy a t56 and the adapter kit to fit the 5.3 block also a company makes a shifter adapter as the shifter is towards the very back of the t56 and the adapter would allow me to have the shifter knob very close to where it is as of now. i just didnt know if you can buy a motor seperate from the pcm and just buy a pcm from another truck if its not available with the donor motor and still have it reflashed and tuned to work. i have been talking with a guy who did a 2002 5.3 vortec and t56 swap into a 1994 chevy like mine. so i appologize for the mispost
