I recently had a huge off idle stumble with my carbed 6.0 Ls engine. The only thing that worked for me was going to a 50cc accelerator pump with a #40 squirter. I also run a .570 lift .228 @50 duration cam. And very large intake runners on my heads "260cc". So I was not getting much velocity off idle. Zero stumble now.
