I'm about to order an MSD bullet distributor and have a question about the install. I know how to install it, but would it be okay just to mark the position of the stocker, yank it, then stab in the new one and line it up to the mark of the stocker? Or do I have to do all the bs like pulling the plugs so I can manually crank the engine to 10BTC, etc.

I'd go with the latter on that one bud...
it's not that hard to make sure you get it right the first time. at TDC the rotor should face the intake - maybe a little before the 1st runner before it's advanced.
good luck

Here's the beginning to end proceedure...
Take the coil wire out of the distributor. Pull #1 plug, put your finger in the spark plug hole. Have someone crank the engine until it starts to blow air past your finger. Stop cranking, turn the engine by hand (breaker bar on the harmonic balancer bolt, or put the car in gear and push) until the TDC mark on the harmonic balancer lines up with the pointer on the passenger side of the engine. Loose the distributor hold down bolt, remove the clamp, cap and wires, disconnect the wiring harness. Pull the distributor straight up.
The following re-install depends on the engine being lined up as in the previous instructions.
To re-install, turn the distributor rotor to point to #1 cylinder position on the cap. The#1 position is about 11 o'clock if 6 o' clock is the front of the engine. Line the rotor up with it pointing at the #1 spark plug position on the cap and drop it in: you may have to twist the shaft some to get it to engage the oil pump shaft. Then remove the SPOUT connector plug, and use a timing light to set the timing. The SPOUT is the dangling connector on the distributor harness on stangs made prior to 94 and with a computer controlled engine. 10* is stock for most 5.0s' 12*-14* is good for more pep if you are not into NO2 or power adders.
