I didn't degree it, just installed it dot to dot. It's the cam, lifters, pushrods, and timing set out of my old 360. I figured I should add the engine is in my 78 Fury, with headers, 2.5" duals, A500 trans, and 3.55s. So am I correct in assuming the cam isn't too big, and it should be pulling more vacuum than it is?
confirm it did not wipe a cam lobe and a comp check
I am sure you kept the used lifters on the correct lobe when swaping in a used cam and valve trane.
but going from camed 360 to 318 with or with out mag heads will make it seem like a dog. 
do you run a stock high stall TC in it?

My gut tells me to pull the timing cover. Granted I don't expect the torque of the 360, and don't expect it to run door to door, its still only 22 cubes smaller than a 340, and a lot of people think they're the greatest thing in the world. It's a 318, but with decent heads (Magnum) and a cam....it should do decent

might pull the plugs & do a quick compression test on 1 cyl & post what you get. That'll be less invasive & (may) tell you something in minutes

I agree,but if it were mine I would rule the wiped cam lobe out first before tearing the front off of it. i have missed them by a tooth also,it happens. but swaping a used cam over is a 50/50 shot if you ask me,the lifters are in new bores and may not spin on the lobe to make another break in run...you did break them in again right? did you lube the lobes up with break in lube?  i have done enuff of that on my junk and went roller for that reason in 07,300,000 miles on a set of rollers and the cam is in its 3rd engine. I have had t-gears with dots off and have had cams ground off specs. it will act like you describe also,I just try the basics first. run a comp check use the piston stop and recheck damper/dist/itermed shaft/ plug wires ect... before tear it apart. I know going from the 318 with 360 heads to the 318 with #302 heads i had to take alot of timeing out of it compaird to what it was at. went form 10* BTDC to 2*-3* BTDC before I got it to level out and dial in. result will vary from engine to engine.. maybe your just over advanced or to much timeing retard have you set the timeing with a vac gauge hooked up to see what the engine likes? then check with a timeing light.

pull the dizzy out and move it over a tooth...might be you don't have the dizzy in the right spot and it looks like you're waaaay advanced. if that doesn't do it, then pull the timing cover and degree in the cam.

That wont matter where it pointed if its got the
proper amount of timing... I dont have my dist
pointed to where the factory shows them to be...
I have it pointed at the #1 plug

does not matter on sb mopar...as long as the cap and rotor point to #1 at the same time and as long you have room to move the vacuum advance and it does not hit the intake manifold...
I know, but....if the dizzy is off a tooth or two, you might actually have the rotor under plug #1's terminal if you put them on the terminals they are supposed to be on what is shown on all the diagrams, and you're actually reading off what should be #2, so when you try advance it to where you want it to be it's way too advanced....been there, done that, I knew something was up when it ran best with 13 or so degrees of initial RETARD, not advance. unbolt the dizzy, jump it over one tooth (or move the plugs over 1 terminal) and all was hunky dorey....

I always degree my cams even in stock rebuilds.
The 440 before the last one I built had a brand new Cloyes Tru-Roller timing chain and .528 MP mechanical.
When lined up "dot to dot" the cam was 8* retarded!
Mis-stamped gear? Cam off? Who knows but it would've run like crap if I'd installed it that way!

You can't move a Mopar Distributor a tooth or two. It only goes in two ways. They have a slot not a gear.
Just lift the intermediate shaft and rotate it a tooth or two

then you just move the whole distributor...LOL..it does not matter...but if you say so..go for it..LOL...
No 1 on the rotor could be pointing at the firewall..and if no 1 on the cap is pointing at the firewall and the wires are in the correct sequence it will run just fine..the immediate shaft has no clue what is going on with the distributor...

I know. I could have just popped my wires over one terminal on the cap to get everything lined up, but then I had issues with the vac. advance hitting the firewall when getting my timing dialed in, so I pulled the dizzy, and rotated the oil pump drive over 1 tooth.
I'd play with the timing, the OP says it drags the starter with more than 2 degrees of advance, I'd just try tune it by ear retarding the advance first and see where it works best. if pulling more timing out it runs better and better, it could just be the issue I suggested, and easier than pulling the t-chain cover and possibly the head to degree in the cam....
