Injectors

What is the big difference between 24# injectors and 30# injectors. Where do you draw the line for needed one or the other?

Looking at your combo, you probably don't need either. Many people are quick to jump to larger injectors, but most who know will say the 19# units will support 300 HP or so. Unless you are planning to add a blower or something soon, I would just stick with your stock units for now.

I wasn't planning on running them with my current set up. The set-up is forged pistons 10.5:1 compression, Roush 200 heads, z303 cam and a Gt-40 intake.

sorry to ***** your thread but I need a second opinion. Check my sig. and what do you think I should run for fuel injectors. I was running way too rich the last time I had it running(plugs kept getting fouled up real bad). The injector calculator says 36#ers would be perfect but they are like $400, versus the 30#ers for like $220. All computer dynos I've ran my stats in say I'll have like 400 rwhp. Any opinions?

With your combo I would run 24# injectors.

You are way overinjected.
