step one, pull the #1 plug and place the tip of your finger over the plug hole and rotate the engine until you feel COMPRESSION build as the number one cylinder, piston starts its compression stroke as the mark on the damper gets close to the timing tab, then remove your finger and continue turning the engine until the timing line on the damper aligns with the timing tab (0) TDC
once thats done the engine should not rotate any more until the distributor is seated correctly.
once thats lined up you drop the distributor into the engine so the rotor on the distributor points at the #1 cylinder when it seats and you install and lightly tighten the clamp and connect the wires, connect the timing light and set the timing at about 6-8 degrees BTDC at idle as a start point., if the distributor won,t fully seat the oil pump drive shaft needs to be turned a few degrees with a long large flat blade screw driver and re-try seating it while, it might take several tries until it lines up, it will seat into the distributor base gear once the oil pump drive aligns with the oil pump slot in the distributor gear base

be aware that some damper designs do tend to fail over time!
beating a balancer onto a crank, pulling it with the wrong type of tool, or letting it get fuel or oil soaked can damage a damper, this can easily result in the outer damper ring with the TDC mark rotating to a random location

if your front crank seal leaks, over time it can dissolve the elastic, between the inner and outer damper hub weight, beating on a damper tends to hurt the flex ring seal alsos
IF YOU CAN,T SMOKE THE TIRES AT WILL,FROM A 60 MPH ROLLING START YOUR ENGINE NEEDS MORE WORK!!"!
IF YOU CAN , YOU NEED BETTER TIRES AND YOUR SUSPENSION NEEDS MORE WORK!!

What if the piston does not hit the stop? I have AFR 195's and put a piston stop in and can turn the piston right past it.

Im forced to assume your referring to the type of piston stop that screws into the spark plug threads, Image

in most cases, simply extending the center threaded section far enought will provide interference to piston movement, but if it doesn,t then youll probably need to pull a drivers side cylinder head and use one of this style

DROPPING THE DISTRIBUTOR BACK IN

without a decent timing light and a well marked damper, on which youve carefully verified TDC, your basically guessing at timing

looks like its impressively exact does it not?
its a distributor hold down ,mount to make it easy to make minor adjustments, well it absolutely useless without first verifying the engines , tdc,and the indications match reality,and thats best done with a degree wheel, and a basic understanding of what your doing

Image

start with the basics, verify tdc (top dead center)on the damper and timing tab are truly indicating TDC
if you don,t start with this TDC info verified , your chasing your tail
