anybody have documented results to show its a worthwhile swap (along with corresponding TB) as opposed to the infamous LS6 intake swap?

36# I believe, but they are ls2 style injectors and you will need new connectors or adapters to hook them up. You will also need to adapt it to work with your return style fuel system since all the TBSS have a returnless fuel system.

After looking at a couple tunes I think they are probably closer to 31# injectors depending on pressure of course. Here is what's in the tune for a 2007 TBSS for injector flow rate vs. psi.

Either way I think you would be better off with the 42# 8.1 marine injectors for a 408 build.

Alrighty, I'll do that. I knew of a couple threads going where people were swapping but I never saw any final results. I may have missed some threads/updates though.

Here is the best info I have been able to find.
http://www.ls1truck.com/forums/lsx-t...-swap-how.html

I have a TBSS intake sitting in my garage waiting for install too, so I've been researching what needs to be done. I am planning on using my existing fuel rails and 8.1L injectors. I think the only issue is going to be getting the crossover tube to fit over the larger intake. In the above write up the guy has access to someone who made a custom crossover out of an exsiting one and some braided stainless line. I don't have those resources handy so I will be attempting to bend my existing crossover tube to fit.
