My dads 82 351w used motor came with a non vacuum advance MSD dist.Is there a mark on the dist that tells you which way faces the front.I found TDC and lined the rotor up with number #1.But with my dist with the vacuum advance I always point the hose inlet forward.That always gives me a good starting point for timing,and alignment with #1 TDC.I hope this makes sense to someone.  ------------------

Ron i have the same one.Mine has the part # on the back of the shaft where # 1 is.There are to clips that hold the cap on one has a little grove peiceabout 1.5 inches to the left of it the other clip on the cap does not. the one that does not have the little grove next to it is the on you use as a ref point then two contacts to the right is # 1.Directly across from the #1 the wires go into the housing on the bottom.

it makes sense to me, but I think it is arbitrary if you do not have a vacuum unit.If you have the rotor lined up with #1 terminal and the engine is a TDC firing stroke on number one, then the only thing dictating the position of the distributor is the gear mesh. If you want to re-orientate the distributor, pick it up and re-stab it with the gear on different teeth. This will force you to rotate the housing of the distributor to once again make the rotor line up with #1 terminal. The reason the vacuum units faced front was for ease of maintanence. Its really up to you. I have seen some with slightly different angles, some point left, some point right and some are straight down the middle. Of course once its stabbed you will need to adjust it a little to get the timing right... Am i still talking about distributors?

Bruce I understand almost everything you said.But where does the clip without the grove part point towards the back the side ect?
Thanks for the help.
Right now the wires coming out of the dist, are across from number one.

Ron the one with out would point towards the thermostat housing the wire going into the bottom would be in front and on the left a little as you look at it from the front..Bruce

Ron TRUST ME THIS IS HOW YOU INSTALL IT.
Facing the front of the motor with your left hand place your index finger over the clip with the groove then slowly turn around till you are facing away from the motor now your left hand is on the left side of the Stang facing the way the distributor will be installed. Carefully transfer the distributor from your Left hand to your right hand and make a full turn in the direction that you turned when you had the distributon in your left hand originally. you will find out that the distributor is now 180 deg reversed. Install the distributor in the block. with the rotor pointing linearly parallel to the crank shaftand the rear of the Stang. Of course the Crank shaft should be at TDC on #1. Now you may have to turn the crank to line up the oil pump drive, just make sure that you return it to TDC #1. Now with the distributor installed Carefully turn the Body 180 DEGs again or till the wire harness exit is exiting towards the rear of the Stang. OK so far? now Install the Cap and install #1 plug wire over the recepticle that is directly where the rotor is under. There You go. Now Get Cold Beer. ------------------

Thanks for the help. 
It sounds like I got it close last night.I'm just going to leave it alone.The plastic housing has some screw tabs that rub agaist the RPM air gap intake.Is it ok to grind those down alittle. Another thing how do you set the advance on it. ------------------

Ron,Yeah, or you can drop it in in a new location if you want. The advance is all mechanical as they should be. Changing the springs to lighter ones will quicken the advance and heavier ones will slow it down. SteveW p.s. Not making fun of you, it was just f'n funny.
