Plugs, Wires, and Injectors I'm working on my LT1 build, and pretty much the only parts I still have to buy are plugs, wires, and potentially injectors. I really don't know much about this stuff, I've always just used the regular Champion plugs and whatever brand wires that you get from any auto parts store. Here's my setup:
353 cubic inches, stock rebuild with forged pistons, I think 10.9:1 compression ratio
Lunati 60121 cam - 221/229 duration, .549"/.565" lift w/ 1.6 rockers, 112* LSA
Mild ported heads, stock valves, 176cc intake runner, around 250cfm or so @ .550" lift
1. Do you recommend any specific brand of plugs/wires? My brief search before told me NGK TR55, but I'd like to hear some other input as well.
2. Should I step up to 30# injectors, or stick with stock? If I upgrade, what brand is recommended?

Tr55, Magnacore 8.5 wires
you may be fine with the stock 24 lb. Check with your tuner since you need a tune for the cam/heads and ask their $02 on what lb/brand to get as he will advise what he is familiar with for tuning specs.
Ford SVO 30 lb has been a common used one for injectors
