basically science you lift weights it can delay your reaction time meaning making you go slower.
YES.
On older vehicles timing was adjusted through a mechanical means. There are a set of weights that, when spun, (by the rotor shaft) are extended to advance timing of the spark. At low rpm's they are retracted by a set of springs.

Check your timing... it sounds like it's too advanced. As far as I know, you tilt your rotor to change it (using a timing light to measure off the timing belt) or just use premium gasoline (the rumor is that it detonates slower).
Yes, it will be worth getting a broken timing belt changed on a 1985 Dodge D-50. The timing belt can be purchased at any auto parts store.
You will need a timing light with the timing advance option so you can adjust and monitor your changes. Vacuum advance limiters along with mechanical advance timing weights and spring kits are available from after market suppliers.
Does it have spark?, Compression? Timing?
Usually start out at about 8 BTDC and advance a little at a time until pinging is noticed, then back off 2 degrees.
If getting fuel and spark, then need compression and air.
If it has an older style distributor with the Duraspark unit then there are springs and counter-weights in the distributor that rotate the electronic trigger to advance the timing. If it is the newer TFI distributor with the computer then the computer advances the timing based on the rpm. If it doesn't have a distributor at all and has individual coils then the computer controls the timing. This is based on what I know about the 2.3's from racing them. Hope it helps.
I believe that it is a non-interference engine which is good for you. This is a complicated procedure, so I would start by getting the manual for your car, then a friend who has a timing gun , and who has set a car's timing before.
getting the marks aligned correctly is important to insure the amount of power you will have.
