Here is what I found on my car.

1. The factory Magnum manifolds will not clear the power steering box. They do but are about 1/8" off of it, so the box would suffer heat problems.
2. Magnum Headers will not clear the steering column so I am going with LA engine headers.
3. The factory Motor mounts for a 74 and older car will work fine.
4. You will need a LA 360 oil pan and pickup for you car. Not hard to get.
5. The Magnum's are a different balance so make sure you use the correct flywheel/flexplate & Torque converter.
6. The van power steering pumps use a different mount and you will need it to clear the battery.
7. If you use an A-518 OD tranny you need to replace the cooler lines with 3/8" lines. The 74 and older lines were 5/16" and are too small.

I hope that helps you some. I will post Wiring diagrams tonight when I get home from work.

Sorry for the Hijacked thread.

Can you raise the engine by shimming the mounts ?
1/2 inch ?....3/8 ?
Dan

The problem with shimming is the through bolt may not clear after it is shimmed.

I didn't try on my car because I am trying to use the factory keg intake which is dangerously close to the underside of the hood.

Here are the wiring diagrams for a 73 Rallye & Standard dash. These are B body diagrams but they are nearly identical to the A & E bodies.





Daniel here is a link to the Magnum Wiring diagrams. There are 12 images so I didn't link them all. If you can't get them let me know. Wiring Diagrams

Ok.....after a trial fit , TALL is the word !!! yes...after everything in place. and keeping my 67 mounts, if I shim the mounts 3/8-1/2, everything clears, and the hood closes fine.

But it is a thight squeeze I have 1/4 inch clearance on the pass side shock tower.....LA headers will fit on the MAgnum heads ????
Do you have the same mounts as I do ?
Daniel

Shorty headers do not clear the steering column ?

Daniel

I have been blown away with work but I will get some pics of what I have done and update.

I will probably start a new thread that isn't about wiring for that.

I will update tomorrow.

Have a good one

Good idea about that new tread !!

So far, i tried with only the engine..no tranny
I'll try the combo tomorrow.....

Daniel

Sorry it took so long but I made a new thread here.

I can take pics of anything I am doing and add them.
