6.2 turbo conversion using 6.5 parts article

a few years ago i read an article on this site that was about converting a 6.2 to turbo using 6.5 turbo parts. since they dont make the banks kit i think this is my only option. can anyone point me in the direction of that article. I am swapping out my 454 in my moho 1999 fleetwood southwind 34l. 454\4l80e. I have in my other moho a good running 6.2. i can pick up a 6.5 for $600 unknown condition but told it was running great excellent condition, comes with the 4l80e trans as well, or theres a local lb7 with allision 1000 $3000 complete truck which i am really considering. im figuring out all the considerations,

6.5 likely will be the easiest simniliar wiring everything should bolt right up and in minimal fuss

lb7/ allison 1000 wiring, sensors, motor mounts and the engine is considerably bigger same with the trans so im taking a bit of a risk there for sure not going to start carving up a motor home.
