LT4 Injector part numbers
Does anyone know the difference between part number 19420334 and 19420801???
Also ive been reading there are 3 types LOW/NOMINAL/HIGH flow. Can anyone tell me the differences between them with flow numbers??? Part numbers??
Rock auto has the 19420334 for $446 a set but Summit and everywhere else has the 19420801 for $518 so im trying to figure out which ones to get.

OP you have came across the same issue all of us have been dealing with since the LT4 injectors came out, GM has not published or released any injector data or flow rates for the LTx injectors. All I know is that you need the sets all matched at the end of the day.
