Does the 1999 6.0 need anything specific to hook up to a 4L80E?

The 99 6.0 has the "long crank shaft" like the previous version SBC.

yes if it is the extended crank version you need to use the flat 6.0 LS flywheel with a special converter that is made for that setup...I've been through this road already...

yes extended crank with stock flat flywheel.
I got a 4L80 that came with a convertor, do you know the measurements from the edge of the trans bell housing to the convertor mounting bolts location?

 

[Convertedfromv8]

I don’t know the measurement but the main thing is that you measure converter pullout and it is in spec with what your converter Company reccommends.

going to be using a stock converter, just don't know the year vehecle it came out off

as long as it's the longer crank 1999 converter. you can't just use any stock 6.0 converter.
