ls1/trans swap...
I am reading and reading about swapping an ls1 into my 80' vette. I did the 200r4 trans swap, trashed the trans so now it time to move up in the world. What are some of the "little things" you have run into doing the swap? I have read articles but they never talk about the small stuff that usually adds up in the end. Also, my vette had a TH350 then 200r4... should I go with a T56 or 4l60e? I prefer manual but if it’s going to be a PIA to swap I would just stick with the 4l60e. Whatever input you have would be appreciated.

Go 4L60E if you stay with an auto.
If I had to do it again, I would have probably taken the extra month or so to convert over to a T56!!
For a 1980, you'll need the high pressure fuel pump set-up, either out of tank inline as others have done, or try to get an 82 tank with in-tank pump (best option for keeping the pump cool) and trans crossmember for a 700R4. An OEM 82 crossmember will work, or a BTO 700R4 conversion crossmember will work.
See my swap for some idea of whats involved:

I am trying to find out all I can on this swap because the Marfa Presidio Open Road Race is in October and I want to have the car ready by then.
