Ok I'm planning on putting my 2003 6.0 into my 04 1500 with a rebuilt 4l60e, I heard the stock 4l60e converter will not bolt up. ? Anybody know ? ( I did tell my transmission builder that I was planning on putting in the 6.0, which he said he'd beef up the trans if we needed.

 

There are a lot of threads on it. BTW that 4L60E won't last too long if you plan on making any power. I'd upgrade to a 4L80E.

 

So true. My "built" 60e lasted lass than 2500 behind my stroker.
