Does anyone remember what the ones sold for 454ss trucks were lb/hr rating wise? They are GM injectors but I believe jet might have done something to increase flow...

IIRC , they were advertised @ 90 PPH , but they were never advertised with a tested pressure rating , making the 90 PPH rating useless .
I actually think I might have a set in the shop , but would have to dig for them as I haven't seen them in years ...........
Use what you have , hopefully you have the 17084304 (service part # 17112560) 454 injectors, this platform is proven to be the best starting point for high pressure applications such as what we are trying to do with them , I have found that the 5235231 platform injectors get "lazy" as you start adding pressure. FWIW , both sets are rated 80PPH @13psi straight from insiders at GM
