I have a 91 Chevy 1500 crew cab short bed. I may be getting my hands on a 2011 express van with a 6.0(l96 I believe) & a 6l90e Tran. My question and it may be a dumb one would that 6.0/6l90 work for a swap on my 91 chevy. Really I’m concerned with the size of the tranny (if there is a size difference) any good helpful info would be great and very appreciated!!
