MPH you showed would probably get you 97 mph in the 1/4 and a low 14. Your 10.65 would probably be a lower 9 in the 1/8 with traction.

That's actually a pretty good gap- about what I have with a Magnum manifold. I've seen them a lot closer with "ribbed" manifolds, to the point where people have hammered the fenderwell for clearance. You've got room for engine movement, so I think you're good. You'll never be able to easily...

Iron manifolds of one of the jeeps are supposed to be good? The magnum pilot bearings will work but you may need to trim the input shaft length a touch, or just rough drill the back end of the crank for clearance and use the magnum pilot.

Think that is the numbers on my intake. I'm sure a cam change , headers, aluminum intake and a 650 would wake it up a lot..probably get 50 to 75 hp gains

How much do you want to keep running a slant-6? The 225 is inherently inefficient by design with the super-long stroke and heavy rotating assembly. If I was to ever intentionally own a slant it would be the 170 variant. I think that would be the best bang-for-buck move in search for MPG and...

...for the big ones that I know of are 53006619 and 53006618. I believe that they were produced for 1992-1993 only. There may be other magnum manifolds that have 2 1/8, but unless mistaken these 53010187 and 53010186 are identical in outside appearance, but have a 1 7/8 inside diameter on the...

I know guys who ran that in 340's with squeeze, & like YY1 I ran the B version in a 383 with the stk. '66 9.2:1 in My case, no power brakes when it's chilly out until it warms up a bit. I ran a 4-gear, no way I would run anything less than a 3,500stall with that squeeze, & I'm talking 383... I...

either edelbrock or knockoff airgap, good thing about the knockoff it bolts on both LA and Magnum.

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...

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...

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.

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

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...

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...

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...

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

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...

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...

How does this 270/280/108 cam compare to the Hughes one below? They never have it on their website but seemed to be a good runner in an almost stock 5.9 magnum a guy on YouTube had. Always was curious and the cam in this thread reminded of just based on some of the numbers.

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...
