Default So which is it??

I've been doing a few searches and reading info on upgrading injectors on a H/C set-up. I have read some conflicting data and am wondering which is true. I've read that 30lb SVO injectors will suffice due to our fuel pressure, then I read that they will be nearly maxed out and should go with 42lb injectors. I currently have a cam/full bolt-on car and am collecting parts to install a set of stock ls6 heads. When I had my car tuned, my tuner let me know I'm at ~95% duty cycle with my stock injectors (26lb, I believe). Adding the heads will push me over the edge.

I'm hoping to put down about 400rwhp with my very mild H/C set-up and want to know if 30lb SVO's will be enough or not. Does anyone have a straight answer?

with a mild setup i'm sure the 30 lbers will be enough,i think the more wild setups are the ones that are on the high side of idc for 30 lbers.

I'm planning on using my 39# Cobra Injectors (which when ran at our pressure will be equivalent to a 42# injector) on my 396.

The 30s will work but for the money spent go to 42#s they tune great and you can spray dry over the top if you feel the need.

Thanks for the info guys. I'd opt for the 42# injectors, but funds are kind of limited. I'm getting a good deal on a used set of svo 30# injectors, so if they'll provide the fuel needed for these mods, it's all good.
