P5153590 Fuel Injection Kit Install

-
Why is this kit for 360 crate motors only? I'm guessing that the injectors are set for 380-400 HP?

Why couldn't this be used a 318 with the HP range?

The intake manifold in this kit is specific to the Magnum small block; and then the injectors rails are specific to that manifold. So you'd have to source an LA 318 intake with injector bosses and the fuel rails to go with it.

Semi correct. The kit was developed out of house by a magazine (I forget which one, MoPar Action I think,) for the 360/380 create engine.
It has a computer with it and is so mapped for that engine specifically. Use on a 318 would probably have it running rich on the low end since torque production is lower.

The 360 & the 318 Magnum engines use the same exact manifold and would also use the same frame rails. The injector size would probably remain the same as it is a HP dependent issue more than cubic inch. Adding injector bungs to an "LA" intake is the way to go. Getting a intake with injector bosses (specifically) is as far as I know impossible.

The computer would have to be messed with to fix the issue.
 
Is this computer programmable? That's my "big *****" with Mopar computers.......

As far as I know it is not programmable, which is why it would only work with an engine in the 375-400 horse range as was intended. As alluded to by Rumblefish you could play with the injector sizes if you had a combination (cubic inches, cam, porting etc.) that could flow more air.

But if you're really deviating from the intended application you're probably better off with one of the myriad other systems out there.
 
I have this kit on my Barracuda. The prior owner installed it. I think he also changed the cam and had the heads machined. So it has some backfire occasionally. I found a couple of shops that can tune the ECM. Basically its a 1999 ECM and components. Tuners that can tune 1999 Dodge trucks and cars can tune this.
