39 lb injectors big enough?
Building a 408 N/A when I get home from Iraq with ported L92's and am using a stock L76 manifold with a Holley 90mm TB that I bought used. It still has the factory 39 pounders and I'm wondering if they will be enough to feed it or not. Could you guys let me know if anyone else has used these and if they were big enough? If not, what size has been used before? Thanks!

There's a formula that calculates the injector requirements based on hp goals, maybe do a search on here to find it. I use the Delphi 42-lb injectors for my setup and the injector duty cycle is at 75-77% at wot.
