To simplify- the voltage correlation makes, don't worry about what a particular scanner says or which direction the reading is. It should be near 4.5v wit the engine off, and much less with it idling.

I plugged the scanne into my dads truck. He reads 29.8 inHg with te key on engine off and 16.8 inHg while idling. After doing te math you guys said, he is at about 13 inHg at idle which is correct for his cam. So I am not worried about the MAP sensor anymore. Here is a pic of the numbers on the TPS. These are the only numbers I could find...

If you want it, I have my OEM TPS that I took off last year. It developed a small dead spot that would make the torque convertor unlock for a second if you were cruising and hit the exact throttle position.
Other than the small dead spot, it's the factory sensor from my 02 and it was working perfectly. It would be good enough to use for troubleshooting and it's free

Hey Josh, just a quick FYI from someone who sold almost all those aftermarket brands for years. Wells ( now Airtex/Wells apparently ) was the absolute bottom, most garbage stuff usually. Standard Motor Products was one of the better, if not the best one availalble. If you have a choice, and the price is similar, run the SMP stuff when you have a choice please
With that said, your TPS readings on the scanner didnt seem to be out of line, so I dont think it is an issue honestly. Also you have had the same problem across a couple of different TPS's, so that indicates to me that the issue continues to lie elsewhere.
Honestly, its looking more and more like maybe the next step is to check the veracity of the mechanical stuff...

Well i'll be the guy that says it, it could be your flex plate giving you trouble, have you ever had the trans out and looked at it real good? I've seen people gouge them up and cause really strange issues, about the only way to test it is by scoping the signal from the crank sensor while running or cranking, in which you need a graphing multi meter or scanner

That flexplate comment made me remember. ..
A Friend had a missfire problem for EVER, finally found the flexplate had broken and was jammed together with the notches all out of place, it ran, but very badly. Its a wonder anybody found that problem.
G-Man
The openings for the crank sensor are square openings on the outer edge of the flexplate. Check to make sure that they aren't mangled or distorted. This is how the crank sensor does its job, by sensing the coming and going of those square openings. If they are off even by a bit, it can cause havoc.

Dave said he got the cam from ME111 and installed it himself. He said his fsm told him to install it dot to dot so that is what he did. Is that correct?

Magnums are a bit goofy when setting up the ignition, but dot-to-dot is fine for installing the cam.
The goofy part is that dot-to-dot is cyl #1 TDC exhaust. You must crank it 360 degrees so that both dots are at 12:00 to put it at #1 TDC compression before installing the distributor. Standard SBC or SBF is dot-to-dot on #1 compression.

So you are saying line it up dot to dot. Install the cam, then rotate it to TDC compression stroke #1 cylinder. And set the dizzy?

Out of curiosity, let's just pretend his cam is installed incorrectly or his distributor was set wrong...would that truly be causing a high idle issue? Isn't it just a high idle problem he's having? Would the damn thing run at all if the cam was installed dot to dot on the #1 comp stroke?
My step mother legitimately thought you could raise boneless chickens.
edit: she once to her taxes to a taxidermy shop...my hand to god, this woman is a moron
It is a high idle and rough idle / drive ability issues. But yea, also wondering if it would run at all if the cam wasn't installed right

The main thing were suspicious of is the cam timing. We already know that your distributor drive shaft and distributor were installed correctly from the pics you posted, so that's not an issue.
However, if the timing set was installed one tooth off, the cam timing would be wrong and it would run, just not very well. Also, some of the cheaper timing sets are known to be less than perfect, sometimes just dot-to-dot could be off by 5 degrees or more.
Pulling the accessories, water pump, and timing cover, checking the cam with a degree wheel, and reassembling everything should only take a day or two.
