I’ve been out of the LS game for a long time so I’d like a few opinions on my plan. I know it’s been discussed in the past, but it’s been a while I’d like to try a fresh discussion for a N/A engine.

I think I’m going to buy a set of 12580426/25326903 FFV injectors, unless there’s a better choice for the money. These can be had for ~$200 on ebay.

1. Do these injectors have enough “headroom” to eventually support heads/cam? I’ve already installed the Texas Speed 220R cam/springs/pushrods.

2. Think the stock fuel pump will keep up?

3. Tuning shouldn’t be an issue, but is there anything else I’m not accounting for? I’m going to run E85 full-time so I don’t see a need for a fuel composition sensor.

 

i would get some 8.1 marine injectors

 

I did consider this but the marine injectors are cost prohibitive at ~$400.
