I am going to attempt this swap and was curious does any one have any idea to what extent the transmission tunnel will have to be modified?

66 lsa on the way, hope this is the case

I have made up my mind to place the order for parts on Wednesday. My only reservation has been cutting up a perfect floorpan. Many cars I have restored it would not have mattered , but this one is clean. I am gathering parts for this build, TCI subframe, frame connectors, 4 link, coilover rear.
First time to replace engine with something other than what could have been so I am sure there are going to be some surprises.

hopefully I wont have to cut anything

When inquiring about fitting issues with a 4l85e it was mentioned that the 4l65e was the same size as a 700r4 , but 4l85e would probably involve trans tunnel mods.

4L85e is bigger....I dont think you have to cut the floors but you do have to dimple them.....I hope you have a lift and a trans jack....i think that tranny is 290lbs:eek:
