Time for injectors??

[286 rocks]

Well, i pulled my plugs the other day and they seemed a bit white for my tastes. Of course they still have a slight hint of brown on the very tips, however..... being my first 5.0 I'm not sure if this is normal. I have a 190lph pump and a holly AFPR already installed but I'm not sure if my injectors are becoming a weak link in my combo which is....

88 GT-


Stock block 306
GT40P heads
Chevy BB Dbl Valve Springs (Don't ask.)
Comp 1.6 RR's
F-303 cam
GT40 Upper/lower intakes
FRPP headers
O/R H-pipe
U-Drive pullys
Smog/AC removed
CAI
MAF conversion w/94-95 MAF
....and that's pretty much it

Anyone think I'ts time for 24lbs injectors or will my 19 pounders suffice for now?

Your 19's will work but I would put 24's in.

Your 19s should work. I ran 19s with a very similar combo, change the F303 for a TFS stage 1, and had no probs. I believe that jrichker has posted how much hp each type of injector will support.
