Awww, come on ....with a good tune and right amount of fuel (buddy also has 8.1L injectors) these motors will do 150 all day. Only thing you have to watch is the trans. That wouldn't be a problem though if you got a built one.

Yep, a 150 shot will be fine and i dont think you'd have a problem with stock injectors. i ran it on my old 4.8 and never had a problem.
