I have a 67 Dodge Coronet with a 360, I want to put a set of Dodge Ram Magnum headers on it. I know they will bolt to the head, I'm just wondering about any other clearance problems. From what I have read online the starters are in the same spot on both engines. The magnum headers dump at the rear of the engine.

Steering column and transmission linkage will most likely be your issues with rear dump manifold. Don't know anything specific about this mod so hopefully someone with experience will report in. If you have the manifold hold it up to the head and see if you can spot any conflict points??

I typed a response for using the magnum manifolds until I read the post again and noticed it said headers. If the header route doesn't work, I'll post again with the manifold post which I did on a 73 B Body. good luck

In my 70 Challenger I could not run the Magnum manifolds or headers because it would not clear the Steering column.

I used regular LA engine headers and they seem to fit with no problems. I haven't started it yet but the fit and gasket contact seems fine.

I installed a pair of 360 Magnum manifolds on my old 1973 Charger 340 Rallye - they are a NICE design! LH side fit perfectly - no interference anywhere. The RH (passenger) side interfered with the trans dipstick tube. I had a new tube assembly made & all was well - no fit problems after that at all. Very easy for my exhaust installer to make a 2.25" system off the manifolds. The only mods the manifolds required was grinding the divider of the two center ports - it's a little too fat. That was very easy to grind/taper them. No gaskets either - just bolted them to the heads with no leaks.

Thanks for all the reply, new to the site. Sunroofcuda was both manifolds rear dump?

One thing to consider is that 66-72 B Bodies and all E Bodies are fixed K frames and 73 & later B bodies are isolated K frames. The Steering may not interfere on a 73 but still interfere on your 67 B body.

Additionally the 67's had a different inner fender well than my 70 Challenger but they still used the same K frame, control arms and nearly the same frame rails.

Since Magnum manifolds are a dime a dozen it wouldn't hurt to try them just to see.

yeah I agree, I found a set for $40. So i'm going to get them and try, plus I have a 85 D150 muscle truck I want to try the on too. If they fit I found a set of Stainless racing headers I want to put on my truck and maybe the car to.

Well to let everyone know, magnum headers will fit on a LA 360 in an 85 Dodge D150 truck.

Headers are those welded-up tubular things.

Exhaust manifolds are those heavy cast-iron things.

Your statement can be taken either way. What do you mean?

And why wouldn't Mag exhaust manifolds go into an '85 truck? The first truck they went into was the same body.
