Sounds like you do. I usually see people going to bigger injectors when they're hitting 85-90% DC @ WOT...

I'd highly recommend FORD SVO 30lbers

I am running a 355 with LE2 heads and a CC503. On 30lb SVO's I run at 60% cycle duty. I talked to LLoyd and asked if the 30 lb SVO's with be large enough for the LE2 cam and was told that the 30lb SVO's are like running a Dephi 36lb injector. When the SVO's and installed on a GM the lb rating is increased according to Lloyd. Hope this helps.
