I're read a ton and cant quit figure out what combination of spacer and flexplate is required on this swap. If I've read correctly the LQ9 crank is shorter out the back of the block and that stock it uses a flat flexplate. So everything that I have read on this swap says that I need the Flexplate spacer to offset that shorter crank. But, with the flexplate spacer, is this enough to mount the flat LQ9 flexplate to a 4l80? or will I instead need to buy a LQ4 flexplate that has the raised bolt mounts?
Hopefully that makes sense, I'm about half asleep. Any help at all would be great. Looking forward to having all my little parts purchased and on the way this week so i can begin the search for a good motor and tranny ASAP.
