Anyone using Precision fuel injectors? What's the word on the streets? I'm looking to run a 236/242 .624/.576 110+4 cam on a 383 LT1. Will I need larger than 30lb/hr injectors?

I've never heard of that brand of fuel injectors before. Maybe that's the reason for the lack of responses. Where did you find them? Most people use the SVO injectors from what I've seen (and used) over the 10 years with my LT1. I now have two sets of 30# SVO's and one set of 60# Mototrons(for the T76 Turbo I'm installing this summer).
As to the sizing, I think you're undersized with 30# for the stroker and that cam. BTW, Are the figures on the lift reversed? I haven't seen any Chevy cams with such a split in favor of the Intake. Most Cams for chevys seem to have larger figures for the exhaust. Perhaps when you ordered the cam and sent a flow sheet, the cam grinder deemed it to breathe well enough for the exhaust that you just needed more Intake?

It was recommended by Patrick G over at ls1tech. The high lift intake number is b/c my heads flow well @.600 and I looking for mid range and top end pwr, since going 383 will bring the rpm range back down a bit. The overlap also helps push the powerband back a bit as well. All in all it's a 4000-6500 application.
