Just can't get the timing right and it has no bolt 1980 Chrysler lebaron 3.7l

You aren't 180 out if You are lining up the rotor at TDC right after the intake closes, unless You're turning the engine counter-clockwise!!!
Or like you say; if the piston is not at #1 TDC compression.

OP;
The #1TDC compression is the principle player.
The cam could be anywhere, taking the distributor with it and giving an erroneous intake closing point. Everything has to be referenced to #1 TDC compression.
EDIT: you probably know this but on Mopars the #1 cylinder is always the first one on the crank making it the the furthest forward cylinder.
