so im gettin my 80e finally and am wondering if there is anything i should look for while doing swap...what tweaks have to be made? i have 05 sierra ECSB Z71 w/ 60e coming out. i know that things have to be tweaked in order to fit but am unaware of what those are, any help?

 

Use the search there are countless threads.

 

My 80E was from a 96 and it had the integrated bell housing with the cast aluminum bolt on converter cover and on the passengers side there was an ear of the bell housing sticking out too far and was going to hit the passengers side header, I have long tubes. I had to trim that off which in the process also trimmed off one of the holes for the bolt on converter cover. No big deal really and I'm not even sure if the one piece bolt on bell housing would even have that interference but its worth mentioning.
