Looking To put bigger injectors on my 89 5.7 TPI. Not Sure what I need to do Tuning wise. I was thinking 30lb injectors. Any Help appreciated

 

Why do you need 30# injectors? That's serious overkill, especially if it is a stock 350.

 

I was told to try 30# injectors but that sounded a lil to much thats why im asking for some better input. I have hooker headers going to a 3" hooker exhaust, K&N Filters, Accel Plugs Wires and Coil and an MSD 6AL Ignition Box. Any ideas for more power would be greatly appreciated

 

You could try a bolt on 383 for more power. If that's a lot, next step may be heads/cam/intake. It's a BIG step but they all REALLY go together.

Just to give you an idea, I wanted to do a few bolt ons for my build. By the time I'm done, NOTHING will be stock on my motor except for sensors.

 

Gut out the bottom of the air filter box. You will see gains from this free mod.

 

For what you have on your car now, 30# injectors are serious overkill. Take a look at all the mods in my sig and you'll see that even with all that I am only running 24# injectors and they provide plenty of fuel.
