Default 5.3 safe?

I've been trying to figure out what parts have a possibility of failing after I'm done installing everything, here is what I'll be running:

1. Yank TC - 3000 stall
2. Street tune
5. PaceSetter LT headers w/ Y-pipe
6. TR224 cam w/ Comp 918's
7. 4.10 gears
8. FLT Level 4 trans
10. Eaton posi
11. Full bolt-ons

And by the end of this month I plan on adding a 75-100 shot as well, but I won't be spraying very often. Is this too much for the 5.3 when on the bottle? Are there any stock parts that I need to upgrade such as injectors etc..? I'd hate to blow this thing, though a built 6.0 does sound nice! Any help at all is appreciated!

sounds like you have a good combination of parts there. i know my injectors are maxed out (103% d/c) however i'm still not running lean. i would upgrade the injectors to be safe side cause you'll probably need them with the spray.

yep... looks like a great parts list, however, some 8.1L marine injectors will drop right in there and you'll have absolutely nothing to worry about even running a 125 shot.

For what its worth see my mods and know that Im running stock 4.8 injectors without coming close to maxing them out.

Thanks for the help everyone, I'll probably be searching around for injectors pretty soon.
