Question stock injectors big enough?

I have a 99 ls1 with a 236/236 @.050 ,,,590/590 lift 112lc with a stock heads no other mods, just a cam and maybe headers later on down the road? Will the stock 26 lbh injectors be big enough? thanks for your time TC

Yes the stockers will be ok. I would put the headers on at the same time If I were you.
You wont see near the gains with stock manifolds they will choke the hell out of that cam. And there will be a little more room with the coil packs and everything off. No would also be the time for a LS6 intake, you have to take it off anyway.

i would think youd be ok, but every car is different.

i have a 240 duration cam with stock heads and i ran out of injector (~102% DC) and i had the 28.8#. the only way to tell for sure is to get it tuned. i would have some ready if you have to drive far to a tuner or want it done that day for sure.

I was fine with 233/239, FAST intake, LT headers, and ORY through a cutout

Yeah, you should be alright but you'll want to keep an eye on them. I've got a 228R, LS6 heads and full exhaust and I'm on the verge of needing more injector. As long as they don't have a ton of miles on them you should be fine for awhile.
