Well, my first official post here. As the title states, I am in the middle of swapping my 4L60e to a 6L80e, yes, behind the L31. I've done countless hours of research and contacting companies on how and what the swap would entail. Some of this swap is trial-by-error. I haven't really seen any forums/posts of folks swapping over to a modern transmission behind an older engine, but in fact, the reverse. I see threads on this site talking about a 6L80e swap, but with gen 3 and up engines. So...I figured I'd take you folks along my journey if you're interested. And yes, I do have the means of swapping an LS, and yes, I have argued with myself about how much of a waste of time this could be, etc... I don't need power as I have a Whipple'd 2014 Silverado, and a built 2010 Camaro SS. But I do like different. The goal is to keep it as simple and cheap as possible going this route.
Without boring you with my life story on where I started with this... I've got the 6L80e, modified the L31 torque converter (168 tooth), and just purchased the TCM-2650 from zerogravityperformance to talk to the TEHCM. One problem that I am very unsure of is the 6L80e torque converter's snout is too long, and thus I pose my question for help to you folks: The bolt pads are about an inch away from the flexplate. Keeping in mind I need at least 1/8" of play, would torque converter bolt spacers of that length mess with anything?
