In '78-'79 or so Mopar smallblocks went to a smaller, offset thermostat. Magnum and Chebby size (maybe slant 6 size too? Dunno.). Most aftermarket manifolds are sized for the earlier thermostats and housings.

The factory Magnum kegger manifolds are easy to modify & will make pretty good horsepower if they are modded right. Unless you're doing high RPM drag racing, they are great manifolds for the street, easy & dirt cheap to get + they make good low-down torque. Check out Utawsome Performance for...

Good find. I run some 340 manifolds on my R/T heads and had to get adapter cut like mentioned in that post. Some of what it comes down to is how the heads were cast. When I was putting my motor together, a buddy of mine had a set of Magnum heads on the bench and the material around the port...

Conversion motor mounts, correct exhaust manifolds for the A body, or make Magnum manifolds work, and you will need the transmission from the charger. Larger radiator. A few wiring changes. Upgrade the differential and when you do, you'll need a shortened driveshaft. That's the basics.

...go with the header flange. Just mock it up ahead of time and check your clearances. If you don't have power steering, you can get Magnum manifolds to work. Passenger side drops right in, and the drivers side will need a bit of shimming/grinding but has been made to work. And regardless of...

ive used a couple magnum 5.9s. An LA 360 car pan works. I used an LA timing set. I did use the magnum accessories to get the serp belt set up and higher amperage alternator.I used la headers on magnum heads and magnum headers on la heads. no leaks.

Just a note - first year of the 5.2 magnum was '92. '93 for the 5.9 magnum.

Wondering about manifolds for my '69 dart 360 magnum. Manual steering, column shift for now but may convert to floor shift. I am wondering whether it will be possible to run a magnum manifold on the driver's side or whether I should track down a 340 manifold. Of course the other option is to...

Right now my plan is a Chinese knock off air gap and early abody exhaust manifolds for my 5.9 magnum. Pretty sure I'm wanting to go with a eddlebrok 1905 650 cfm. I'm keeping entirely stock internals. Let me know if I'm being an idiot. This is just a street car

Yea I got one of the speedmaster air gap intakes on Black Friday a couple years ago. I'm gonna use it on my magnum

I failed to mention that a Magnum engine will require an electric fuel pump as it does not have the components to drive a mechanical fuel pump. This is a dealbreaker with some. A Magnum engine will be a little more work such as outfitting it with the LA timing cover so you can run the LA V belt...

i found this. wonder how bad the exhaust manifolds mismatch. Magnum Swap: Chrysler LA parts - what works and what doesn't? |

91 5.2 is a Magnum and was rated 235 HP with the "large exit" Magnum manifolds. Rating went down to 230 with smaller outlet manifolds. 5.9 was rated 245 HP and was the same build as the first gen "crate" 360, rated at 300 gross HP.

Have a pair of the 360 Magnum ex manifolds. Matched pair $150. Located in Goodyear AZ. Shipping not included

I had 340 manifolds on my on my mild magnum build, went with the cheap summit headers, and remflex gaskets thread locker on bolts. I’ll never go back to manifolds the amount of torque I gained and h.p was worth it!

...magnum manifold fits. What I haven’t found is a definitive answer on the drivers side. Do they or don’t they?!? Has anyone used magnum manifolds on the driver side? Any pics? I have a 340 and the car is a 904 with manual steering/brakes. I’m trying to let the 340 breathe decently without...

My bad, I thought I saw it somewhere. Maybe it was someone modified an early to accept the later by enlarging the bolt holes And using a tapered washer?

Yep stock magnum heads with 340 manifolds had that combo for years then swapped to headers still using that same part number gasket with headers now. Remflex Inc. 6004 Remflex Exhaust Header Gasket Sets | Summit Racing

Yes I think you’re right. Because when I put my old thermostat housing on the M1, it was too big and I needed to get one for a magnum, so does this mean that the larger one is standard for LA intake size?

I have seen threads on this forum with this discussed before and I believe the EQ heads have extra casting material around the ports to allow 340 manifolds to seal. The magnum heads from Hughs may also have the extra material.

Based on the pictures on the website, the only iron Magnum head Hughes lists doesn’t appear to have the needed material to seal 340 manifolds. Plus they have the Magnum intake bolt pattern and would require the extra cost of redrilling them if you wanted to run an LA intake. The aluminum heads...

Keep in mind, if you start using studs that long, you will NEVER be able to remove the exhaust manifolds once the engine is installed; there's just not enough room in an A body engine bay. And no, exhaust gaskets weren't used on LA exhaust manifolds, other than the tin heat shields/plug wire...

very early dakota on the pass side. and then pretty much whatever fits on the driver's side. i think mid 90's dak have the magic on those.

SendCutSend can cut stuff for you. I have a pattern I gave someone here recently for this exact reason. Can't promise it is a perfect fix, I have the same problem (Magnum R/T heads with 340 manifolds) and my adapter plates seem to be ok. But I have leaks I haven't identified so it could be...

You also have to grind on Eddie 318-340-360 RPM aluminium heads and manifolds. I did a little on each, so as not to have to grind to much in heads or manifolds. It is due to the fact that they used the same casting as late heads where there is a threaded port below the manifold for smog cheap...

My drivers side ex manifold I tried would hit the steering box. how did you get around that?

Nope. The bolt holes are different. LA angled (almost 90° to the head) and the magnums are vertical. Some new manifolds have dual bolt holes.

Shipping a fortune. Hughes sells new Magnum heads prob sufficient cast iron around ports for 340 manifolds. So you can spend your way out of head aches buy new Magnum heads LA intake bolt pattern likely 340 exhaust bolts on no adapters improved castings that don't crack quench chambers erc...

So it looks like the exhaust from the LA manifolds are compatible with the Magnum engine. So my headers should work. What about the intake manifold (SB-LA to 360 Magnum)? If not what manifolds are there for a carburetor set up on a Magnum?

Just out of curiosity….are the exhaust manifolds header compatible on a 340 vs Magnum 360? Meaning can you swap headers from a 340 to Magnum?
