318 exhaust manifolds on a 360

I bought every style Magnum drivers' side manifold in every variation I could think of; 5.9 Ram/Dak/Van/Cherokee, 5.2 ditto. I literally had 9 driver's side manifolds from Magnums, all different.

ONE fit and cleared everything. The outlet pointed straight at the torsion bar, dead center, with about 2" to make the bend.

Dougs' headers it is!

If you want manifolds, buy the 340 set and move on with your life.

Treblig, I don't know you, and I don't have a dog in the fight, but you're not doing anything new and you're certainly not making many friends or customers doing it.


First off I'm not looking to make any friends!! Second, if you've bothered to read all these posts, I've already sold one of my manifolds, (Sold, paid for and delivered). Third, I was trying to help the OP by answering some of his questions about 318 manifolds on 360s, sorry if I was under the impression that we were supposed to help each other. And as for not doing anything new.....I hadn't read anywhere that the Hollander number's were different for the smog port and non-smog port so I ended up buying a ported manifold by mistake by using the casting number. I don't want other's to spend their money on something they don't want. I had also never read that the one manifold (9377) was for a Jeep engine with the starter on the passenger's side. Maybe everybody else knows this fact, if they did they never wrote about it??? I researched this issue for many months and didn't read anything about the Hollander number. If you already know everything there is to know about these manifolds that's great (please tell us) but, if you've read the previous posts on this thread, you'll read that I also was questioned for not giving all the information I had. It was a misunderstanding, but now you're jumping on me because I'm giving too much information.
I'll let the majority decide if this information is useful. I'll sell my version to those who want it and to those who want to use the manifold as cast, well it's their option. I know that I'm not the only person who either doesn't like headers or can't afford them BUT I still want to get as much exhaust flow as possible.
As for buying 340 manifolds....I guess you haven't noticed that many members aren't rich!!! If they were they would all buy 340 manifolds until there were none...then what??? For those who are not rich...Here's a fairly inexpensive alternative, modified or not!!!


The information you just posted is great but we all need casting numbers to avoid the manifolds that don't work??? You wasted some of your money on manifolds and I wasted some of mine, I was hoping to help other FABO member's save their money.
