You're very unlikely to find one for a deal used, most would have to be bought new. Yes, you can do get a Magnum bolt pattern 4bbl intake.

You could buy a Magnum 4 bbl intake. Or you could redrill the heads for the LA bolt pattern and have access to 44 years of intakes. Which makes finding a decent intake secondhand easier. Including the fact that those that came on the cars and trucks were decent.

If you use Magnum heads, you either need a Magnum intake bolt pattern 4bbl intake or to redrill the heads for the pre-Magnum LA bolt pattern. The vast majority of intakes were and are for pre-Magnum LA intake bolt pattern. That's why there are many available significantly under their original purchase price.

I see...so it'd be better to just get the heads redrilled...will i be able to still use the mag holes later on or no?

It's a possibility. Mine can still be used. I just used RTV in the threads like always and it seals.

hmm..it doesnt matter to me whether i use the mag or la bolt patterns, because i plan on buying a new intake no matter which one. This motor will be run a lot, and run hard from time to time, so IMO, the new stuff is the way to go.

Ok, so would the 91 dakota rt headers work on my M? Like for when the magnum gets put in, cause I believe it was those that were the best so I've heard. Am I correct or no? I figure if I can find some, I won't have to worry about if they're sealed or whatever, cause they're meant to be stock..or so I would think.

There is no such thing as a 1991 Dakota R/T.  A 1991 Dakota is the last year for the LA engine in the Dakota, a 318 with a TBI.  Magnum engines came out in 1992, the Dakota R/T started 1n 1998.  Dakota exhaust outlets are both at the rear.  Figure the passenger side could be made to work, the driver's side would not.

I thought I had read dak rt on a separate thread on here...kinda wondered why I couldn't find on . And I have my plan..just waiting for the motor. I've budgeted my checks to allow me to start saving fr the parts. But if I can get a set of headers that flow better, fit better, are coated already, and are cheaper..I'm going to.

And I don't want to stick a big block in this car for a few reasons..but mainly just because I don't want one. Eventually ill find a car with an excuse to get one..but not my DD dip

Unfortunately the explaination is on page 1.

No Dakota R/T until the '97 redesign. First V8 Dakota in '89 (Shelby), '91 was first factory V8. '92-6 were available any cab, any bed. Only 318 before the R/T, the R/T had the 360.

The passenger's side is the one that's better than a 340's. Some have posted on here with F or Ms with Magnum exhaust manifolds but no pictures nd no extra details unfortunately. The manifolds are still cheaper than 340 manifolds and have the same collector size.

Well then maybe it was a 91 just the 318 dak. Ill have to look it up again. As of now, its the stuff like that that I am still thinking about, but I know that the swap will be for a 318 magnum engine. I've found the ignition, the summit headers, and the intake and carb. The dak. Header option, and the cam are still what I'm contemplating. I'm between getting the magnum cam reground, or just getting a new one. I've decided I'm going to have the heads redrilled, and if possible, use my intake until I can get a new one. That way I can get it in faster, and move my funds to other things.

This entire thread of 18 pages may seem unnecessary to those of you who know a bit about this, but to me who knows nothing..it was very helpful. As I said a while back, this is the first car I've ever actually worked on, let alone contemplate a motor swap..so hearing all the different opinions helped me get a general idea of what's best. Thanks to everyone fwho has contributed to not just this thread, but in helping me get a better understanding for all there is to know about these things. As soon as I get this motor, ill let everyone know, and as the build commences, ill be sure to try and get as many pictures up as I can.

If you are looking for Dakota headers, I have a set of JBA's if you are interested.

Will they fit on the dip? I don't have the motor yet, but once the ball gets rolling on that project I may look into those..if they'll fit and are what I'm after.

Good lookin out though..ill keep that in mind

Thanks

Probably not. Just get cheap F/J/M headers.

get the LA summit headers that are coated.  pretty much any "shorty" style truck header will have clearance issues with the brake booster, and possibly the power steering box.  there are some edelbrock ones in 409 stainless that looked promising and come with a Y, but I didn't want to spend $400 to find out they wouldn't fit....
