What size injectors?
After finding a good sized oil leak, I decided to pull the motor and rebuild it. Long story short, I got carried away. New crank, rod bolts, rods resized new pistons, new heads, lt1 converted intake, new cam, balanced, and so forth. I need to get new injectors before I start the motor, but I don't what size to get. I was thinking 42# but am worried they might be too much. The cam is a 230/236 .571 .596 114lsa and 11:1 compression on aluminum heads. I have not upgraded the exhaust yet. It still wears the stock manifolds, pipes, and muffler. What size injectors should I get, and is the exhaust going to really hurt me for the time being? Thanks for your help.

42# is way too big unless you have a blower. You probably want to go with 26# maybe? I think theres a formula for this (hp expected vs injector size).
Also, yeah your exhaust will hold you back.
