I think you would be surprised at the flow of the 318 manifolds. Nick's Garage tested the magnum manifolds And the 2 1/8 manifolds only produced 3 more hp than the 1 7/8 ones

Sounds like the driver side is maybe 1-7/8? To the OP (@dodgegtdart68), are these magnum manifolds?

I think maybe that test isn't valid. I am concluding this based on the dyno test on YouTube where a JY 5.9 was compared to a 300hp crate motor and they made within 1 hp of each other. Exhibit A - even though the crate motor had a better horsepower producing intake (in theory), they made the...

Obviously lost power with manifolds, but my headers were junk and this was easier. It pulls really well with a stock 383 magnum torque converter. Flashes to around 2700. Set up the Mopar performance distributor to 22 degrees initial and 38 total. Lots of initial timing is key with this cam and...

As all Magnum engines were only installed in trucks(it was a truck engine) you would have to kow if there are many different driver side manifolds available over the years. Non magnum 360 manifolds would be an option. I caught the word Gasser in there. Why wouldn't you be running headers anyway...

I'll check out both manifolds

67 and 68 383’s are very different. 67 383 had closed chambered heads and a small CFM AFB with the narrow bolt pattern. A bodies had a one year only left manifold with the most restrictive dog leg. B and C bodies all had log manifolds on 383-4bbl 68 383 all had 906 heads with a 2806301...

I think that 55hp increase is a smokescreen because it's without accessories, an air cleaner and with headers. That's the only way he got a 300hp crate motor to make 300 hp. And don't forget that a JY 5.9 with the same setup but with the beer barrel intake and EFI made within 1 hp of the crate...

For Sale 2 5.9 ( 360 ) Magnum short blocks one with heads and exhaust manifolds ( bad rod bearing ) one just the short block , good for rebuild / stroker project or core, must sell $200 each or best offer

I’ve tested a few real duds over the years. But the ones that come to mind had some pretty notable deficiencies. Here’s one...... 396bbc. Oval port heads, Comp 280 Magnum cam, ex manifolds, Ede 750, and the big problem...... an SP2P intake. I don’t remember the tq, but it was low 280’s for hp...

I have a set of manifolds off of a 2000 ram 5.9. The opening is 2in. The motor is a stock 2000 5.9 other then a carb conversion..... Reading on this site, dual 2.5 in. exhaust seems to be the recommended size. My question is, are most of you converting the 2in to 2.5in at the manifold? If so...

Those Magnum manifolds should work in a truck, although you might need to be creative with the PS pump and brcket if it has that.

Thanks Thought I measured pretty close to clear Let you know, tho.

A '90 is not a Magnum, it's a roller LA. It's neutral balance, so you may be able to make the flywheel work- I'm not 100% sure, but I recall the 273 having a smaller crank register (OD). You may be able to have your flywheel bored to the later diameter or find a later 273 flywheel to bolt up...

Right I didn't word that great, more like 20-30 lb-ft across the board and 30hp PEAK gain. It seems to run out of breath somewhat around 5800 RPM. I have the shorty headers currently and not only are those mediocre at best themselves but I feel like the tiny 2 1/4" head pipes that snake super...

Any magnum Its going in a D100 wont have the clearance issues

I am running those same manifolds on my MP R/T heads and I had to get some plates cut to run them. The material around the port on the head was too small to seal the port in the manifold. I've seen OEM Magnum heads where there wouldn't be an issue, but I've also seen one's with the same...

You could source a Magnum manifold off an early Jeep Grand Cherokee for the right side locally. If it has the big 2 1/8" outlet, they say it flows as well as a right HP manifold. And that is the hard to find (i.e. expensive) one too. Left side you need any HP manifold for an A-Body. The...

On a 300hp crate 5.9l magnum, they did 318,360,340 manifolds and made 311hp, 314hp and 315hp respectively they didn't have magnum but there around 340 output. headers they had shorty, 1 5/8, 1 3/4, tti and made 321hp, 319hp, 319hp and 327hp respectively. other than the tti there's barely any...

Redo the heads. Depends upon how far you go. 5 angle valve job with 70 degree bowl cut and bowls opened to about 88-90 percent of seat size, chambers unshrouded and last seat angle cut blended into them, and heads decked to raise compression, then 50 hp may not be out of the question. The...

...from a 72 scamp , i bought another set of open chamber 318 heads and another 2bbl intake to rework them a bit , i have a couple of magnum manifolds laying around too , im planning to remove a bit of weight on the fury but not much , its huge but nkt that heavy , i really want a cruiser...

The Base is the 300hp crate engine which is a stock 5.9l Magnum with a 4bbl intake M1 dual plane and 750 holley and headers. Seems about right with his 288 hp with beer barrel and manifolds.
