I'll most likely have one for sale in about 2 weeks. It's from a 97 Cobra, for 42# injectors, not sure if that's a different plug than the Foxes though.. I can find out once I have it since I have a 5.0 to try it on.

it won't fit. And if it is a stock cobra it is not for 42lbers.
Thanks anyway.

I'm running a 357w, Vortech S-Trim, 42# injectors with a Cobra 80mm MAF. My Speedbrain is telling me I'm exceeding the MAF capability so I'm stepping up to 90mm. Just mentioning this as I noticed you're running a similar setup - you might want to skip the step and go right to 90mm. Just a thought... If you decide you really want the 80mm, mine is for sale but is calibrated for 24#.

I was pegging my 75mm bullet Maf. So I did some research on corral etc and saw a large number of people using a 80mm.
What kind of hp are you running. I would think with a 357 you are underinjected at 42lb.

My Speedbrain is telling me I'm developing a ridiculous amount of hp. I'm going to put the car on a chassis dyno before I make any claims. If you crank up the fuel pressure, you can make the injectors think they're bigger. There's a formula for it, but I don't have it handy. I am running the 42# over 90% duty cycle, but not even at full throttle. Gotta be careful I don't go dangerous lean - forged assembly or not, it wouldn't last long 
Haven't gone bigger than 42# cause it is a street car, and with the 80mm MAF pegged my fuel/air curve is in no-man's land so I can't yet mat it (sort out one issue at a time). I have a wide-band 02 system to hook up to it, but haven't gotten around to that either. Anyways, 80mm MAF is right out of there for me. I got my paws on a 90mm Lightning MAF with conversion harness. If you like, I'll take a pic of the harness for you so you could do the wiring swap (our cars use the same sensor) and go straight to a Lightning MAF (which are also calibrated for 42#).
