I rebuilt my 68 340 block in the early 2000s and used magnum heads on it. After having one set with cracks I just bought new bare castings. Back then all the Mopar magazines said that the 340 hipo exhaust manifolds bolt right on and they were right except you eight huge exhaust leaks. I...

Some info in here on running 340 manifolds with magnum heads: 340 manifolds and Magnum heads

I had magnum heads with 340 manifolds I ran remflex gaskets for a magnum engine no sealing issues

what inter changes between a LA and magnum small block. stuff like timing chain, timing chain cover, oil pump and oil pan. distributor ? will 340 exhaust manifolds fit a magnum head? i know the intake is different. are the LA accessories able to work on the magnum?

thank you.

What I ment was aftermarket manifolds.

My point. No manifolds were dual pattern except the late model LA/ Magnum I takes.

Did you use them on a stock magnum head? Maybe this is the answer.

...be the '92-93 Magnum manifold that has a larger outlet diameter than the later ones, casting numbers 617/618. Even the standard Magnum manifolds don't give much up to the larger bore ones or the 340 manifolds. They all will take some horsing around to get them to fit an early A (even the 340...

Magnum manifolds would SEEM to be the logical answer- they clear the manual box but may need to have the column sleeve trimmed back; not sure if there's enough clearance to do that with a column shift. May need a bit of grinding to clear the shaft/coupler as well, and/or a swap from coupler to...

Some of the M1 manifolds used a smaller thermostat, maybe the same one as used on Magnum engines. Your new manifold is probably specced for the one used in V8s from the 1950s until the Magnum came out.

Just a note that Magnum manifolds hit the top of a PS gear box. They clear a manual gear box, though.

I dunno that just doesn’t look safe, that motor would have to be chained down because if it shifts up it’s going to push on the steering shaft. Wish there was some better picture cause it looks like it’s resting on the manifold……….

No! No early manifolds were dual bolt pattern. LA and Magnum yes.

i have some d truck manifolds I can try on a junk magnum head tomorrow if it helps.

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.

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...

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?
