word, 19#'s. I'm currently running 28.8# car injectors. According to Justin I have PLENTY of fuel with my cam and bolt ons

 

it hung up there for a while... about a thousand RPM on the pull... and it was in the peak of the tq curve. I'll get a graph/log to email to you if you want. It will take me a couple hours to get it though. The guy pulling it wouldnt get out of the throttle

 

At your current shift point. Once you're ready to bump that up, your fueling needs may increase.

 

Ouch man, that would have upset me. At the very least, you're missing out on a decent amount of power. You've gotta be down in the low 12s at the leanest to safely make good power with that shot...

 

yeah, I wasnt happy... It made noises and blew **** out of the cutouts I have never seen... I'm still babying it. I'm going to pull a couple plugs and do some looking with my borescope today too.... I just want to see how close my #7 is to shitting on me...

 

we will worry about that when the time comes Let's help out Ben here. Ben I picked up my 28.8# injectors for $35 shipped or something like that. Spent $20 on 2 sets of the MSD-2400 pigtails from Summit (got an extra set in case I messed up the wiring). Maybe $5 in wire, another $5 tops in mounting hardware since the stock fuel rails are up higher since the car injectors are longer. So that's $65 and for now my fueling needs are supported. I would think they would cover what you are shooting for also but then again I'm not sure what your future plans are. If Justin thinks that they won't cover your fueling needs I would try to find a set of the 31# injectors or even 44#s. Good luck let me know if you need any help on how to wire them up they were very simple to do.

 

I am doing heads and a bigger cam in the future. When I do these injectors, I dont want to do injectors twice. Plus, this motor's getting bored to 5.7 so I'll need something to support those cubes, a nice healthy cam, heads, and a 200 shot... I think the marine injectors are what I need.... I wont be going bigger than that.

 

By my calcs, 42#ers will give you plenty of fuel for what you're wanting assuming you're running a wet shot. With a real well flowing setup, you'll max out at about 65% IDC if you spin it up to 6400 rpms... 70-75% at 6800rpms. Single 255lph fuel pump should be fine too. You'll only be taxing it up to about 3/4 of it's capacity...

 

4.8 making 335 rwhp spinning it to 7000 on the dyno im at 71% duty cycle with ls2 injectors.

 

Yea look in my sig...
