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 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...

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...

...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

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...

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...

there also a 440 with hp and standard manifolds and a few hp difference. And yes the two small block manifold shoot outs were 300hp create engines.

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...

I run one in a 74 Road Runner with a 4 speed. I used the Magnum exhaust manifolds (92/93 Dakota) with it too.

The Edelbrock RPM is the best power maker. The Chinese knock off intakes are cheap as heck and do OK at best.

The last ford I worked on head shaft rockers...

Like I mentioned before. If you are only doing heads or only doing cam, I think the cam will do you the most good. If you are thinking about adding the other later you might as well keep what you have and build a engine with a purpose. Like me and my 70 318, It has dual exhaust and a Pertronix...

He's right about the sealing. I think the chamber design on the Magnum is better than the LA, but now you have sissy stud mounted rockers like a Ford, so to me the heads are a wash. They come with roller cams which is a positive. The block is a shorter deck height for more compression, so that's...

Yes, we are having a ... REALLY .... HARD TIME ... and I mean REALLY tough time selecting one of two options ..... I thought I drew up the parameters really straight forward and easy to understand. :lol:

I measured the center pair of manifold port flange thickness on the 340 pass ex manifold & it is 1/2", the same as the magnum manifolds but it overall is way wider. I took the magnum manifolds in to be machined & i told em to take off 1/4 which is a 1/16 more than recommended but I am getting a...

Here is the cam I had in my 340 before I replaced it with the 408 Magnum Stroker I now have. Long tube headers, LD-340 intake, Dual point distributer. 750 Holly carb. Worked great! [SOLD] - Purple Shaft Cam for small block

So far im loving these magnum manifolds. They look some what factory and its super easy to get to the plugs. Im glad I went this route vs headers.

And just to give you how much more you have to look forward too........ Our full size B250 Van with a full size bed, a table, and chairs ran very low 10's in the 1/8 mile with a stock 360 magnum (4bbl and headers). Just get your car to hook up and you'll see the time drop massively. 2.8's 60...

So from me selling off the 302 heads and intake a and all the other stuff here’s what the swap cost. LA BLOCK SOLD parts 250+275 (intake and heads) =525.00 80.00 (rocker arms) =$605.00 Magnum SOLD Parts Valve covers $85.00 Manifolds $80.00 =$165.00 Total sold part for swap $770.00 BOUGHT...

Do you know the size of the bolts? I know its 5/16, not sure of the length

IIRC you have to use the Magnum bolts into the heads' water jackets. Can't use studs here because of the Manifolds beefier construction and clearance issues. I also recommend using Remflex gaskets. (I "planed" the manifold faces with a file beforehand.) I've always had an exhaust leak in the...

Magnum Exhaust Manifolds in good condition, 53010187 & 53010186 castings. $20 for the pair plus shipping from SoCal

@dartfreak75 didn't you use Magnum manifolds?

I have a stock 01 5.9 magnum in a 71 dart. 340 hp manifolds, 727, and an 8 3/4 with 3:55 gears. Street only, I do highway drive occasionally at around300 rpms. I am looking for a good tight street converter, any suggestions?

So the Magnum ex. manifolds fit ok, no problems?

The 318 & 360 Magnum heads are identical. Q1. No Q2. Edelbrock’s Magnum RPM. The cheap chick knock off intakes will work OK as well. But you asked for the best. “Edelbrock”

You can if you get a set of the 63’ to 66’ motor mounts, the V8 center steering link, and exhaust manifolds, headers will either be fender well or spitfires. If you look around here on FABO a couple of members have had success with Magnum exhaust manifolds with some modifications. I might have a...
