I don't think the MP folks RE crate engines ever suspected people might use those factory truck and Jeep manifolds in "cars". Of course they really only work in cars that have manual steering. I'd be interested to know if that Borgeson steering box clears Magnum manifolds.

...and weighted converters on 5.9 Magnums and then wondered why their motors sh sh sh shook! lol. As far as exhaust, there are some Magnum manifolds that breath better than the early A specific ones like you have. I think they actually came on Dakota R/T's like the truck your motor came from...

Aluminum heads and roller rockers on that 7 to 1 short block are like putting silk stockings on a pig. I would either buy a set of pistons, or start over with a 5.9 magnum to build.

Agreed. I used Hooker Super Comp headers @ 1-3/4 in my ‘79 Magnum. The current 5.9 project is going in a ‘74 Duster with the standard style 1-5/8 header. I’ve read some headers have an issue with the Magnum motor mount boss. IDK about my case just yet. It’s easily taken care of. This, I have no...

Dig it! Thank You!

After 4500 rpm the torker is better I had good luck with mine on a 340 11 to1 243@50 108 cam it had rhoads lifters so that made it slighty bigger then your cam but you have 20 more cubes of torque . Air gap is hard to beat for a street car. 1 are yo going to race it? 2 gear ratio 3 valve size

Yeah there have been some folks that put them on. I think they only fit the 67 and up cars.

...fair points about the inlet and outlet ports. I'm pulling the 318 manifolds off today and will measure the outlet port sizes, and I'll measure the head port sizes for comparison. Hopefully the outlets are at least the same as the 1-7/8" magnum outlets.

I believe they do fit, there is a thread. I believe it takes a cut down steering column and grind on the drivers side manifold some. Maybe a few shims on engine mounts.

I have some magnum exhaust manifolds if you want them. They supposedly flow better than the stock manifolds.

My Question is will the 66 block and 906 heads And a 440 cam still give me the HP of the 383 magnum that I once had? And will it fit with headers because exhaust manifolds cost as much, if not more than to build a motor.

**** the A/C, open your windwings, the little beer/weed hiding vent doors, and step on the fuckin gas! You will want to get yourself some of these too. I think @hemi71x has some for sale. https://www.forabodiesonly.com/mopar/threads/emblems-383-four-barrel-383-magnum-440-magnum.541348/ You may...

thank you i think i will go with a 340. thank you for your comment.

Can you make the 92 Dakota 5.2 magnum exhaust manifolds work?

Magnum exhaust manifolds. Was going to put them on the ramcharger, but changed my mind. Asking $100.00 plus shipping from 19963

I did it! Magnum 380 crate in a 74 Road Runner 4 speed with power steering. I used the early truck manifolds and an Edelbrock Performer 750. The driver manifold "kisses" the power steering box, but does fit in a 73/74 b-body. Yes, I realize that I am not getting optimum performance from the...

I’ve heard, haven’t used them, that they are worse than a stock magnum casting.

I think (think!) they were magnum motors, but were down-rated because of the terrible drivers side exhaust manifolds (the 440 manifolds are worth a fortune, cause they were thrown away for headers.) Edit: tree'd by Hemi Dart!

Just fyi the magnum and La heads have different bolt arrangement and manifolds do not interchange unless modified. The magnum bolts are vertical and the La head bolts are perpendicular to the intake face of the head. You can get around this with some drilling/tapping elongating holes etc.

Totally agree, great score on George’s part! I’m all in for you getting the ‘93 truck. Magnum 360 in that 1993 truck will surprise you in a good way. Those have the larger outlet exhaust manifolds that work almost as well as headers. If you don’t have emissions regulators to work around...

My machinist set the quench this way on my 408.

I had magnum manifolds on my 66 Valiant before I went back to the slant. I shimmed the motor mounts about a 1/4" and it was Tight! I ended up using a u joint style coupler on the gearbox to gain some clearance.

possibly...but at what rpms? I'm thinking 'any' 318/340/360 manifold likely flows equally enough up to ~4000 rpm to be 'moot' from a performance standpoint, and I've also read they are likely better flowing in the higher rpms...but not by a lot, plus my engine won't be in the higher rpms enough...

1- 98 5.2 magnum complete. has the 186/187 ex manifolds on it. 2- complete 98 magnum under hood wiring harness. 3- pcm. 4- 2000 8 pin 46re w/conv. 5- have the throttle body, p/s pump w/truck and van brackets, alt/ac bracket. engine was pulled from running truck about 9 months ago due to frame...

i never ran a oil filter adapter when i had my early abody with a 318 just used the small filter, and ran the stock manifolds for that year. Same with my 67 and 68 barracuda used the small oil filter with magnum manifolds on passenger side.

I was wondering if a 2500 Stall and 3.23 gears , magnum manifolds or cheap headers / 2.5 double exhaust could make it work....yes i.will cost me a very small amount of money and its a Nos unit still in box , but i dont want to trow 2k On the 318 either, slowly buying parts to duplicate my...

Early A’s use the same K member for v8 and slant. He just needs the motor mount brackets. If he goes aftermarket/Schumacher v8 mounts he won’t need the drop center link, as they raise the engine enough to clear the link. The v8 throttle bracket and the exhaust manifolds are all he really needs...

I am having a carbon problem on my intake and exhaust valves that I cleaned up last winter. It was quite thick on the intake and the exhaust indicating it was running very rich for years. It's all back together now and I'm trying to get it to burn cleaner. It's a 9.9:1 340 with magnum...

Or just run the 65 drivetrain as is since he will have it. Adjust the valves, set the points, adjust the timing, make sure the carb is good, and the vacuum advance is working.
