Looking for a Mopar performance M1 intake manifold. Magnum engine, fuel injected. 2 or 4 bbl.
If anyone has one sitting on a shelf in the shop or knows someone that has one for sale, please let me know.
Single or Dual Plane? I have an M1 single plane I probably will not use.
Sorry for the slow reply. Just got the notice about this post.
Few questions before I get too excited;
1- Fuel injected?
2- 2 or 4 bbl?
2.5- If 4 bbl, do you have a 2 bbl adapter?
3- Magnum, not LA bolt pattern... correct?
4- How much?
5- Any pictures?
1 - Like all M1's it has the bosses for FI if you want to drill them out, but it was never used in a FI application. In fact, it was only installed on the engine but it was too tall for the hood, so they went with a lower profile dual plane instead. That's the story I got when I bought the engine anyway....It doesn't look used, just some surface rust inside the water jacket from sitting. The water gasket you see on top, never been used.
2 - Not sure what you mean here....I suppose you can use whatever will fit on it.
3 - Yes Magnum...Came with a 5.9L magnum crate motor
4 - Dunno...I bought it with the engine, so shoot me a fair price. I'm easy.
Thanks for the time and offer, but it's not quite what I'm looking for.
At one time the M1 was offered as a 2 barrel or 4 barrel fuel injected intake. There was also the option of adding an adapter plate to the 4 barrel so you could use the stock style throttle body.
Yours is a 4 barrel. I think yours is available through summit or jegs for around $400, brand new. Yours is probably worth half that because of being installed. That's just my guess though.

No worries but pretty sure all M1s have the FI bosses and can be drilled for injectors...they're even stamped with the injector numbers as mine is.

That's correct. They can be machined for the injectors. And Mopar Performance sells an adapter for the 4v intake base to mate the FI throttle body to it, as well as the accessories to fit the stock fuel rail.
I'm looking for an M1 also, or an air gap, and the cost of getting the adapter and machining for the injectors, and getting the bits to make the rails work drives the cost of this intake beyond what's financially viable, unless I can get one for 50 bucks. Or, if I decided to swap to carb, which I can't because I have to do emissions tests and I also like EFI.
But I also can't buy it for my Duster project because it puts the carb through the hood. Bummer. It's a really nice part. But a lot of people buy the crate 360 and find the intake too tall for their application, so a lot of these are sitting around or traded away.
Really good intake though, if you have the hood room.
