Year make model. If you are working on a 5.9 Magnum please call it that. Yes, a 5.9 is 360, but it is not a 360. It is a Magnum 5.9. As others said they changed the neck size at some point. What intake do you have? Someone may have swapped intake manifolds, and some aftermarket...

To manipulate my HP with less gearing and convertor for the few times I get the car out on the street, my track day's are long gone. My old buddy traded his Chevy 383 for a 496 in his 70 Nova. lol Him and I and a few other friends did the AHRA thing back in the day. It's been dead for awhile up...

...hipo 440 manifold, maxwedge manifolds, and headers. Headers won, obviously, the max manifolds did very well, the normal 68-70 magnum manifolds, not so much. I don't remember the numbers, anyone curious will have to look it up. But as said above, the more power/displacement you have, the more...

There is another dyno test between manifolds and found that best combo was one 340 and one 5.9l forget which ones but here's non magnum manifold and header shoot out Installing Exhaust Headers Into 300hp Crate Engine - Mopar Muscle Magazine

Ah, what the heck, build what ever you want. Do your homework and search for the proper parts. I have read about some strong 318/390's here. Just a few. Most aren't that attached to the original Teen though. Remember, if you modify it it won't be original any more. Pull it, stuff it in the...

No offence, but you ask, and several people tell you, but now You still have to check and measure between a 66 and 68 ‘to make sure’. Why bother asking to begin with? Many people here have and share a lot of knowledge but it feels like a waste of time when it doesn’t really get used. Early a...

Here's a 282 hp @ 5000 rpm with a xe262h 4bbl headers on stock low cr longblock 318 Long Block Bolt Ons - Tech Articles - Mopar Muscle Magazine here a bunch of 318 related articles

here's all the 318 ones +

And this is what happens when you try to tighten it down. This came to me because the guy couldn't get rid of a bad exhaust leak, no matter how hard he tightened it down. Hmmm... To illustrate the point, here is a head with air injection bosses. I put on the ('64-'66) early A manifold and...

...hp difference. There's been dyno comparison between hp and standard manifolds with no big differences. Same between 340/360/318 and magnum manifolds was like 5hp even shorty headers don't help much need long tube collector to make a decent difference especially once you start going with...

...make more power once you out there exhaust system on. They stated no collector extentions on the headers. All on a stock engine. No Magnum manifolds tested. So I’d still like to see what that deal is worth. Anybody? The factory writings stated the best exhaust manifold combo was the drivers...

Bought a rare LD4B for my 318 ( 1971 casting ) and a bunch of other parts / engine gaskets / copy of an edelbrock air gap / 650 dp carb / 5.9 magnum exhaust manifolds/ dual exhaust set up .............* My big Question is unfortunately the LD4B is massively ported to the 340/360 gaskets , i...

During testing, the air pump cooled the exhaust gas and somehow it reduces the toxic fumes. I don’t know the science behind it. A catalytic converter doesn’t need an air pump to remain clean and clear to do its job. It needs a properly tuned carb. The aftermarket (check around Summit Racing)...

LD4B ? THe previous owner should have bought a LD340 instead of hogging out a LD4B.

EQ aftermarket magnum heads/magnum ex manifolds. thank you for your time. RR

2-3 mpg worse. However! I did manage 20 out of my 360. It was a ‘79-360 in a Magnum, with a OEM 4bbl intake, 600 cfm Edelbrock, MSD 6, dual exhaust off of the manifolds, a 904 & 2.76 gears on 26 inch tires. A 318 is good for another 2-3 mpg’s in a lighter vehicle. The Magnum weighed in at...

Those are the generic Chinese Air Gap manifolds that I spoke of- they are sold under a number of different names and vendors- search for your best price. They fit both LA and Magnum heads, so if you do go the Magnum route down the road, you don't have to hunt down another manifold. They work...

340 Forged cranks are balanced for heavy forged pistons. If you use one with 318 pistons especially hypers, it's gonna cost heavy dollars to balance that up. IIRC those 340 pistons were around 719grams versus like 550 on the stock 318s. Hypers would likely be less. Save some cash, use the 318...

As I am loathe to grind, cut, or hammer things out of shape, maybe I'll have to spring for a set of quality headers after all. I've heard that Doug's and TTI are good, but haven't researched enough to see which of them (if either) don't require removing the steering link or putting on a costly...

...340 "high performance" manifolds which would be the best option and are being reproduced, or 67-76 A-body 318 manifolds (72 and later 340/360 just used the 318 manifolds). You could also use 92-93 magnum manifolds, but there is no ready-made y-pipe for these since trucks had right side exhaust.

...storage and a 360 2bbl carb and adaptor... i really would like to run a dual exhaust system with the fury and good manifolds or even magnum manifolds / headers, im very inspired by little simple mods like 318willrun s pocket porting . I like the idea of running small ports and small valves...

The crate motors came to us dressed as a production truck motor we pulled off the breadbox intake, distributor, exhaust manifolds, truck oil pans, timing chain cover, gear sets, oil pump and pickup, camshaft and lifters, and cylinder heads. Nothing else was removed from the short block. The...

That stroked magnum is internally balanced. You can use la heads on a magnum. La intake manifolds can be modified for magnum heads. The combos seem to be endless.

You'll be close to that by the time you get bungs machined and welded into an existing manifold and have to get custom fuel rails made up- and still be saddled with a "compromise" manifold. Then there's the throttle body adapter and other miscellaneous hardware that's included in the Hughes kit...

I can't give you horsepower numbers or fitment issues because I have a b-body however I have a mild Street 360 Magnum and went from hipo 340 manifolds to flowtech long tube headers and I could definitely feel more torque seat of pants. At the time I was running flowmaster mufflers and the sound...

Sounds like you've been there!

I 100% agree but a couple guys are in the 10s with manifolds nothing better then beating built cars ford and chevys then pop the hood and say like my stock manifolds

Your original statement said the drivers side and both of those are passenger side manifolds. The magnum manifolds are said to flow more so it would be a no brainer which one to use. The ‘92 magnum manifolds had a 2.5” exit, had a couple pairs back when they were new. I can offer no advice...

I took my car to Milan Dragway a couple weeks ago and I'm totally embarrassed on how the car performed. They are going to the 1/8 mile racing, which I have never done before. And I don't like it either. Anyway it ran a 10.65 at 77.5 mph. The 60'...
