I did some searching around for performance intake manifold options for a 97 318 ram. The most popular manifold that I could find is a Mopar Performance M1 MPI intake Manifold. How much work is it to replace the stock manifold with a M1? also, are there any other aftermarket intake manifolds available?
The swap isn't very hard - just remove the old kegger, swap over the components, and plop the M1 in there. There aren't any other performance intakes for the 318/360 beside the Mopar M1 - one question though:
How will you be using the truck?
Reason I ask is that there is another option to the M1, involving modifying the stock kegger manifold. The M1 is designed to work in a higher RPM range due to the short runners - great for racing, not the best for street driving or offroading. A modified kegger can give you power down in the lower RPMs, where the 318/360s like it. I can give you some more info on this mod, if you'd like.
I have heard from a couple of very reliable sources that the low end loss experienced by most who do an M1 upgrade is because they do not flash their PCM to compensate for the M1. There is actually an "M1 Flash" you can get through the Fastman (it's a B&G flash), and it is supposed to make a huge difference. If/when my plenum goes, I fully plan to get an M1 with the appropriate PCM flash. Expect to pay about $400 for the flash though.
edglock21, that info for modifying the stock kegger manifold would be great. I would like to improve both the low and high end power, but if I had a choice, I would rather improve the low end power and torque since I could use that for towing. Hughesengines.com does have a modified kegger manifold (called a stage 2 OEM), is this what you mean? Do you know how much of an improvement this modified kegger is to the original?
It's not really one or the other because that makes it sound like they are equal. The flash is so much better then a hand held programmer. But yes, you would not want to use the programmer with the flash.

Here is some information on modifying the stock kegger manifold (this is all information that I gleaned from other sites, I've not yet done it myself - I just got a second manifold off of a 5.9 that I'll be using though.)
- Take a Sawzall and hack off the runners flush with the runners next to 'em (see blue line in first pic below)
- Clean up the ridges, and any metal shards, with a Dremel (sort of like porting, but not to the same degree)
- Get yourself a Hughesengines or APS Precision Plenum Gasket replacement kit and a Fastman Throttle Body, button everything back up - and you're all set
I'm sure it sounds easier than it actually is, but I'm gonna give it a shot on my newly acquired manifold. Anyone that doesn't feel comfortable doing it, go see a machine shop or call up Hughes and get their modified kegger.
The pictures are property of robert97dodge, from DTO, during his modification of his manifold (I don't claim them as my own and will remove them if requested - I'm gonna PM him over there with a link to this thread).
Fellaz, while the M1 will improve performance, in some states, like here in Cali, it'll flunk the visual when the smog nazis do their testing. With a modded kegger, Hughes or otherwise, they wont know it's modded just by looking. I'm going the modded kegger route. Just my $.02
I don't have any pics of my engine right now. Are you just wanting to see what the M1 looks like on the 318? If so I can take some pics for you. Just let me know.

Here you go JD770. Please excuse the dirtiness It rained a couple of days ago and I haven’t washed the engine yet. Hope these are what you’re looking for.
I would guess 245-255rwhp depending on which heads you have. (1.92-2.02)
Nice video btw
