just to follow up - I discovered the motor mounts in our 94 Jeep Grand Cherokee utilize the LA bosses and not the magnum bosses, and as such I'm using two of the p-side GC mounts on my 02 magnum 360 (one on each side), which gives me all the room I need to use center dump manifolds - simple and...

Aren't truck 5.9 Magnum manifolds a easy swap with lots of flow? The Offy Dual port may choke your engine. I have a 318 sized one I bought from Summit back in 2000 or so on my '79 360 van. The big port 340/360's were out of production. It worked well with the Comp RV grind and 2200 stall...

back about 15 years ago, I picked up a magnum 318 with a spun main bearing for like $200. I took the original 318 that was in my '85 5th ave that had about 65k miles on it, reringed/bearinged it, had a 5angle VJ done on the magnum engine's heads, home bowl port and gasket matched them, used the...

Plus magnum manifolds will only give 5 hp at best.

Thank you this is great information! On the topic of 273 exhaust manifolds, is there any way to get more flow out of them? That might be the only option as I don't have the money for headers.

Are you at least going to use the larger outlet Magnum manifolds?

They can be made to fit, but like I said, you have to be willing/able to do fab work to modify them. Remember, these are designed for later ('67 and up) A bodies, the early As are quite a bit more confined. The passenger side fits fine, however the driver's side needs a bit of work. Stock...

good info! I must be missing something obvious as I had slotted the (manual) steering box so I could lower it some & raised the eng all so I could run magnum ex manifolds for much better flow. I will get on it & see if I can take a pic. thanks a bunch! RR

I’m not sure. I used to have about 12 or 14 for the LA head alone. Let me think as I type…. Ummmm, for the LA; OEM’s, 1-‘72, 1-‘73, Weiand’s 1 Stealth, 1 Action Plus, Edelbrock’s - RPM X’s 2, 1 dual quad/dual plane, Chink air gaps, 2. (Which are dual patterns.) MoPar - 1 each M1 single...

The blocks are identical PN and dimensions, whether the regular 2 bbl or the 4 bbl Hi-Po version. I think that includes the crank and connecting rods. Only the pistons varied. You can buy special Hi-Po pistons today (Egge?), to give higher compression. The 1964-65 heads have bolt angles ~16...

Your plan sounds pretty good so far save for the cam lift. I think your cam duration could be a little higher for one. I did exactly what you are planning, with some slight differences. My Oregon regrind is 214/224 and .512 lift on 110and sound wise I can barely tell it has anything other than...

Truck LA 360 manifolds can be made to work on the passenger side, but won't fit the driver's side at all, power or manual. Magnum manifolds, same deal. Fit the passenger side but not the driver's side with power steering. I honestly don't know that anything "flows better" than the original (A...

The last 20 years all the American manufacturers have had broken exhaust manifold bolts. My Dakota 3.9 Magnum V6 has a few I need to deal with. When they did their design updates from the LA, SBC and SBF they all came up with the astoundingly brilliant idea to save material on bolt...

63 dart 360/904/7&14 circle track. I am raising the eng/trans so I can run good flowing magnum ex manifolds. what is the max degrees offset I can have on the pinion angle? I know I want them within .5 degrees (iirc) of each other & offset parallel. thank you for your time. RR

I've seen one that was internally balanced. It had the counter weights on the crank cut down a little and the throws turned to run 6.125 SBC Scat rods. It had off the shelf .030 pistons for some kind of SBC. I think it got just a small amount of Mallory metal, but it was smooth as silk when it...

the 63 was never designed for a V8 so there's a little more fiddly-ness to get a V8 and 727 in there. the seam in the firewall with need to get flattened out to fit the 727 bellhousing. along with some massage work on the upper wall near the heater/wiper bump out. you'll need to change out...

Well no kidding, I didn't say they would, only that certain magnum manifolds WILL work. I'm not sure what your point is other than you feeling a little jumpy this morning. It's a much more cost effective way to get some "decent" flow on a street car. For what the engine is, they will be loads...

Don't some mill some off the manifold flange to gain room ? Angle mill it ? Not sure kind of remember people doing/saying that. I wouldn't do any engine or suspension moving to make it fit, what are we talking power wise an hp or two, I know all the little gains add up, but I wouldn't do...

Headers didn't seem to make much of a difference on this combo over manifolds.

The street Demon seems like a good carb, pretty much a modern thermoquad. Know a few people that run them and they love them. Definitely get the resin bowl.

5.2 magnum vs 5.9 magnum right from the factory... same heads, intake, throttle body, exhaust manifolds, but the 5.2 actually had the "hotter" cam but the 5.9 still made about 15 more hp. I think you run a stroker now??? Why did you add more crank....????? :poke:

A set of speed pro 2355F would be a good piston for this. Even the summit 6401 is a nice street cam.

Okay that’s awesome thank you! What would you recommend as far as carbs? I almost got my hands on a decent priced 6 pack, is that worth it tho?

Update: So I found an early style magnum balancer in decent shape and installed it but I am still having the same engine "throbbing" at idle and cruising. It is definatley more prevalent when the engine is warmed up. The engine always stays nice and cold. It is not a full rebuild I found a...

I got new heads finally for my 318 . Now I need exhaust manifolds. Do magnum manifolds work ? If not where can I get new style manifold ? I don’t like headers .

No, not at all. I know for a fact and back, that the Magnum manifolds do work but not on all cars without some clearancing, because not all these cars are the same. I have a friend in north Georgia who put some on a Duster, which as we know is a lot wider than a 64 in the engine bay. They hit...

My thought here is the Mag ports are 360 size and my manifold is 318 size Edelbrock performer. I don't want to run the larger intake manifolds as I want to keep the velocity in the manifold high but not restrictive. Are the factory rockers on the Magnum engines adjustible?
