I was just had a wild thougth about mabey a cummins swap in my 94 suburban 6.5l and wanted to hear some of yalls thoughts. Mabey help me find a reasonable price and any other feed back would be great.
Thanks

 

Im about to start mine in 2 weeks. Putting in a 97 6bt with allison 1000 behind it.

 

I'm planning the same thing once my 6.5 gives up. if you want to run your 4l80 you'll need a controller and an adaptor. theres alot of different options for mechanical transmissions if you go that way. you could also run an allison but youd be spendin alot. theres a wealth of info on alot of sites. which 6bt were you planning on swapping in? theres alot less wiring with a mechanical 12v (1989-1998.5 model years) as opposed to the ISB 24v (1998.6-2002 model years) heres a thread build up off of 4btswaps.com

i suggest a donor truck, that way you have everything there to compare.
