Wondering if I should upgrade injectors/fuel pump on full motor build
I'm starting to look around because I'm going to do a full motor build on my ls1 right now I have:
Ported 243's
Tsp 233/239
Forged pistons/rods
Fast 92mm ported
Etc.. I'm hoping to make over 450hp and I'm curious if I should get bigger injectors? If I did would it help me. I also plan on doing a 200 shot and also should I upgrade fuel rails / fuel pump thanks again!

you could just upgrade your injectors, take a look under the fuel and injector forum page, and find the STICKY for fuel and injectors that I made at the top of the page in yellow.

the stock fuel pump, 190Liter per hour maxes out at 38LB/hr injectors, naturally aspirated this would give you ~450hp if I remember right.
if you upgrade to a 255 Liter per hour pump and say 42# injectors, which I don't think you will need THE INJETORS with the mentioned setup you will be good for 50# injectors.
I would recommend some #36 pound or so injectors and the racetronix PnP kit w/wiring harness. This would leave some breathing room on the setup mentioned above
