I agree because it is a stock small engine. MP just outfitted what is basically a OEM 5.9 Magnum with a carburetor intake, 750 carb & 1-3/4 headers to get what they did and label it as 300hp as not to disappoint anyone when it dyno’s more. All stock V8 engines gain power with dual exhaust and...

And another heads up- depending on what you're using for exhaust. If you're running headers, you'll have to grind the mid-block "Magnum" mount bosses down in order to clear the headers. The headers may also need to be modified to clear the 727 at the bellhousing, since it is wider than the 904...

If I remember right the magnums made 1-2 hp over 340 and the 340/5.9 combo made like 1-2 hp over that. I'm pretty sure was done by one of the mopar magazines but been unable to find it.

I think the LA rocker gear is better with the bar system. Oiling the rockers ether way is fine. The shaft has a longer path which is not a longevity issue or problem. The LA system for higher RPM. The Magnum gear will need a little help with high lift cams. A “Girdle “ like the. Chevy uses is...

This is a very rare and early intake manifold cast buddy bar, B/B. I'd ask 600 for it. In a way.. because its obvious.. I find it odd no one has mentioned it ..since we're all mopar brothers

Some ported 234 or 973 casting heads with larger valves would keep the port velocity up and flow pretty decently, but a set of bare speedmaster iron magnum heads would make a better starting point. It is possible to adapt an LA intake manifolds for use with magnum heads (or maybe even drill...

What would I do? 5.2 Magnum with stock EFI and stock Magnum exhaust manifolds, dual exhaust. 32RH/999 transmission- lockup convertor, but no overdrive- so no crossmember/floorpan mods. Direct bolt in to replace the 904. Deeper first gear, and lockup gives a bit more efficiency on the highway...

Hwy funding among other funding areas. New York was under the same gun again years later. The first Gov. Cuomo decided to adapt California emission standards but he was met with resistance in a big way, he backed down. Until the President threatened to withhold A LOT of money for our Hwy. and...

Really? The speed limit didn’t drop until the Carter administration and national disgrace didn’t start until 1977.

They might have been designed for those RPM's but that was back when 55 mph was the general speed limit. And even then, a 3.23 gear and 205/70R14 (E70-14) was only spinning at 2575 rpm at 60 (5 over). I have a '91 Dakota w/ a 318 TBI motor, A500 and 3.55 gears and it cruises at just over 2K...

Im looking at a 1961 model If u locate the needed motor mounts let me know thanks Chris

It has dual exhaust but stock manifolds. That’s why I’m thinking headers or maybe magnum exhaust manifolds from 92/93 maybe. Has a ignition upgrade now. Supposed to have a cam- small rv cam but I’m just gonna say it’s stock cause I don’t know for sure if it’s been swapped or not

...they routed the oil drain / return bung for a turbo setup I plan on putting the turbo near the valve cover on the passenger side. Leaning towards using reversed Magnum manifolds. If anybody could provide their configuration in any respective photos I'd really appreciate it thank you everybody.

My 5.9L Magnum short block with ported open-chamber Edelbrocks "should" be soft on the bottom end with only 9:1 compression... I had the cam custom-ground by Racer Brown and it's not a problem, granted it has a converter that stalls around 2600 RPM but still. It would be better with...

Not true. Old wives tale. Those intakes run great. It was used on this trick 318 build for engine masters that made 477 horsepower. I put the motor in my car, ran mid 11’s with it…. Nothing at all wrong with them. Iron-Headed Mopar 318 Magnum Engine- Popular Hot Rodding Magazine

I recently did the same with my 74 D200, 360 la with Magnum heads. I got the same kind of results as you did. Old truck still runs pretty good, I think it has to do with surface of exh manifolds.

Mostly. Theres always variances in mix per runner but you're spot on.

...(273, 318) are only 1 5/8". Even the '70s 340 passenger is only 1 7/8". There are also some newer 318, 360 manifolds that are 1 7/8", then there are the newer 360 magnum manifolds some of which are 2 3/16". So the demand for the larger pipes for 340 manifolds isn't a big as you would think???

OK, cats on our older cars for cleaner exhaust… gotcha. I haven’t used one on a upgraded engine with a cam. Just on my ‘79 Magnum with exhaust manifolds on a stock 2bbl. engine with the only mods being a swap to a 4bbl. Carter 625 and a MP ignition box since the Leanburn did its normal thing and...

Looking for more low end power. This isn't rocket science. You can achieve this really only a few ways. Biggest factor is gonna be displacement. Another is compression. You need both of these. Without these two things all the cam heads exhaust etc isn't getting you there. If it were me, I'd go...

Agree alot on most posts on this. However, with magnum 5.2 with la motor.mounts (rubber,and important) Can't compromise clearance in 4 spd for obvious reasons. The whole idea I rid the 273 manifolds should also be obvious. I am now modifying 340 driverside manifold from 72 and up duster...

I don't think those '72 Dart manifolds will clear the new PS box- they clear on later As but not on the early ones, the outlet hits on the corner of the power box. They clear with a manual box though, as you know. The Magnum PS pump and bracket from a van will clear the battery tray, it mounts...

1.7 rockers and some springs. Who makes them. Custom cam, engle has the old masters for Hughes. I had them grind one up years ago for a 318 truck motor 'smog' .479 208/216 112 or 114 'cant remember' atm. Its here in a thread of mine somewhere. Get someone to purchase and mail it, or is the...

...em. On a side note I thought the 68-70 340 pass side ex manifold was way wider (maybe I'm wrong on that) than the pass magnum but a moot point cuz I am good right now. I do have a 408 stroker in the works & I'd like to use another set of magnum manifolds when the time comes in an early A body

I bought an 86 Ram D150 a few weeks ago. It has a 318 roller/727 and 9.25 (sure grip) rear with 3.23 gears. I'm wanting to build it for low end torque and fuel economy. Plans are to use an Eddy Streetmaster intake (already have) and spreadbore carb. Also I'll be using early Magnum exhaust...

If you're willing to drive a little bit, I have a mostly complete stock 318. It came with a 904 I bought, and I used it as a mockup to build an engine run stand. Once the stand was done I wanted to see if it ran, and it actually did. I wound up scrounging some parts off it for my Magnum, like...

Nice what kind of aluminum heads? Regardless of brand/type they should have smaller closed chambers than the 906s which will give you a nice bump in compression and much better knock resistance. The Edelbrocks on my 360 are the "open" chamber (more like recessed closed chamber) versions...

Get a set of rod and main bearings also. And check the cam bearings. The magnums had detonation issues because of the valley plate on the stock efi intake manifolds and ate oil which caused them to detonate. 3 of the 7 I’ve disassembled also needed cam bearings. Your keepers just need to match...

340 Mild build and now Stroked 360 Magnum. Had stock 68 manifolds, long tube headers and now using TTi shorties. Long tube had best performance, Manifolds had most leaks, mostly due to mods done to choke (my fault) .Shorties are proving most liveable as plug change is easier no denting tubes to...
