I use Ford Motorsports green top 42 lb injectors from a Lightning. Good for 700+ rwhp at 58 psi.

i run stockers with a 150 shot, going to step to a 250 soon. a wet shot shouldnt need bigger injectors as much.

If you run a wet shot no injector upgrade is needed. if you run a dry kit of that size...injector upgrade and computer tuning will be necessasry.

It's a dry 5177 kit from NOS.I was spraying 150 and it looks like I broke piston #8 and pitted another so I'm going to rebuild and get a stage 2 H/C setup and I wanted to see if I could use the dry set-up for when I run into those pesky exotics there's roming around here.I was looking into 42lb'ers or somthing like that

Wet is the way to go, It is safer. And makes more power. IMHO

With a heads/cam package making 420+, wouldn't it be safe to say that you are already close to max'ing your injectors. If you add even a wet system, to be on the safe side, wouldn't SVO 30# (our 36#) be good to put in? And 42# is a little bit of an over kill?

Well...hes saying he will be spraying a dry kit. That means all fuel will be coming through the injectors. Thinking a H&C package will be 425 rhp...and he wants 200 hp ontop of that for a total of well over 600 rwhp...id say 42 lbders would be just right.

If he went to a 200 wet...his stock injectors would be just fine the way they are. If they were fine at 425 on motor...they will be fine on a wet shot...provided the fuel pump keeps up.
