Yes, I ran LA headers on my 360 mag.

Well you know what they say about opinions. Opinions are asses. Everyone has them. Some folks have better asses than others. I think that's how the saying goes ☠️ Anyway... Nothing in this build screams high mpg daily driver. 350+ gears, 3000stall, 750 carb, etc. At 360 cut in, you're not...

Left side will hit with 64-66 LH or Drivers Side exhaust manifold using 73? up LA heads with the air boss. No problems with 67 up manifolds. Magnum heads have the same small exhaust port and do not have an EGR air port so they should work with the 64-66 exhaust manifold as well.

When it comes to intake manifolds for the Magnum head, there’s really only 4 to choose from unless you find a MP unit. You have the; Chink knock off RPM style The Edelbrock RPM The Indy single plane and the Indy Mod Man with several tops to choose from. The MP dual and single plane are found...

On my mini tubbed Dakota I recently did the intake manifold plenum plate re seal. While the keg was removed I set my Offenhauser dual quad on the 5.2 as well as a Weiand Tunnel Ram. The 273/318 Offy probably will work great with OEM Magnum heads. The Magnum heads have smaller intake ports than...

...OE-sealing. That said, here's some additional thoughts on suitable exhaust manifolds. To me I basically have three options: 1) '02 Magnum manifolds, 2) 340 manifolds, and 3) 318 manifolds. The magnum manifolds have significant physical interference issues with factory A-body power steering...

Following years are 1 7/8

This will probably open up a can of worms as this subject has been well covered but I am interested in some recommendations that folks have actually built and ran. Here are the particulars. Care is a 73 Dart swinger 3.23 geared 25" tires factory high stall converter in 904 with a TF-2 shift...

My TTI step headers have Magnum port shape. I was told at the time that only way they come. So the header flange hangs into each of the 4 LA corners ports, the two front and two rear ports. But its lower corner so impact to flow not as bad. I had a welder add a bead to header flange to...

...for the car weight, gearing, and intended use in it. Top it with a decent intake and either 68 to 70 340 manifolds, 95 and up Magnum manifolds, or a set of headers. The 95 and later Magnum manifolds are slightly larger than the earlier Magnum manifolds, and have larger outlets. Timing might...

What year, body,of magnum manifolds are you suggesting?

I just bought a Magnum crate engine (300hp) from a dyno shop local to me. Going from a stock cam to a small comp (212/218 .480 114) and switching from an M1 dual plane to an RPM Air gap, the thing picked up 65hp and lost no torque anywhere.

Why not use Fel-Pro gaskets and match port the gaskets to fit over the gap and under the exhaust lower port. Should be enough pressor to stop a leak. Never had this issue on a sb Mopar, but I did on a Chevy 350 and had to double up on the gaskets to get a good cushion seal.

92-3 ?? Dakota RT 360 Magnum 2 1/2 outlets very similar in flow to 68-71 340 manifolds

I think you need to do some kind of mod to them, plus there's different ones I think the earlier magnums were better, I wouldn't worry about it, your 360 ones will do.

Not all "magnum" manifolds are created equal!!

They say the exhaust manifolds from a 5.2/5.9 Magnum engine flow much better than the old school ones, you just have to make some head pipe adjustments.

My mind must be gettin old. I wasn't aware some magnum manifolds fit. Thanks

Manifolds... Magnum exhaust manifolds on LA

I see you have the trans installed, is the trans mount bolted into the crossmember? if it is the distributor looks like it might clear the firewall. Exhaust manifolds from a 5.2-5.9 magnum truck should work if you keep the manual steering but you might have to change the coupler from the...

The "good" magnum manifolds have 2-1/8" outlets. Just a tad smaller than late 60's 340.

Pretty sure Dougs makes a drop-in header for a small block in an early A. Probably other options out there too. You could always go with manifolds too. It doesn't take a lot to get these little cars moving.

Nope, too new. The 68-70 340 manifolds are the first choice and the 71-74 manifolds are next best. There are combinations of LA and Magnum manifolds that work well too. There are many threads here on FABO about all those choices. Yes, if the headers are in good shape I would probably leave them.

I'm extremely impressed with how well you hid the BluePrint 408 under all the OEM equipment. The kickdown linkage, throttle bracket, manifolds, etc. awesome!!! you did a great job!! That magnum hose angle is a little weird. we do put a single hose on it, and it's not my favorite thing, but...

Still not as good as headers.

I wouldn't go to the trouble of the swap, if I already had a decent exhaust, but if installing a new exhaust wouldn't hurt digging up a pair.

...the time, but that was 30+ years ago. There have been a lot of new things brought out in that time...as I'm now learning. I'm always open to new ideas or suggestions, that's why I ask questions here. :) Well, crap...now I have to consider Magnum manifolds, too? :) Do they even work on an A...

I would say, if you're not building it to keep for yourself, don't do a BB swap. Find a 360 magnum and build a nice little SB. You WILL lose money on a flip doing a BB swap. Example BB manifolds if you can find them 2 grand, TTI headers 1 grand, most likely aftermarket hood or cut a hole in...

Supposedly the magnum manifolds are the best flowing. Kim

Yes, this was the article I read a while ago. Thanks for finding it. From my understanding, the Hughes intake is a licensed copy of the Edlebrock Air Gap so performance should be similar. Yeah, while I'm waiting for the MAP sensor I figured I would fix some wiring problems. The fuel level and...
