its pretty close i think. but im not sure. lol did your truck 3.7 burn out before the injectors?

Thanks Bobby! I have been running them for a little over a week (last sunday) with no problems. I too thought fuel pressure would have been cut but it's not. The ECM just tells the motor to suck more air, which is why I am doing a homemade CAI today!

I noticed a nice difference just removing my muffler and running spintech. Could actually spin the tires a little on dry pavement. Now with the injectors, as you can see, I can just floor it and the truck will stay sideways lol.

Yup, just swapped them. I didn't know AirRam sold injectors for the 3.7 hmmm. But the 4.6 injecetors are designed for a bigger engine so they have more fuel pressure. (I think I explained that right). If I am wrong Blown please chime in lol. I paid $224.50 at my local auto store, you can probably find them cheaper online, I just didn't want to wait.


Completely stock = Barely. With the exhaust mods it did a little, but now with the injectors the truck will just sit sideways if I try hard enough.

So would the injectors help the 4.7 like they did yours?

good question....my mouse is hovering over the buy it now button for injectors....

I am not sure. I know Blown is running them, (almost positive) but I am sure that there won't be as much of an improvement with the 4.7 as there was with the 3.7 seeing as how the 4.6 and 4.7 are almost identical as far as size. Therefore fuel pressure should be similar. I hope I explained that right. lol

X2 i hope blown can help us out haha.

So did they drop right in or did you have to change anything? And can some one tell me the factory lbs injector for a 4.7?

19 for the standard, and +3.3 for the HO. i think

Are you using the 19-pound injector or 24-pound injector ?

Looks like this and a fastman tb will be my next mods
Does anyone know if the stock piston rods and head bolts can handle boost? If so ny truck might be getting boosted in the near future
