take out the number 1 plug.thats the passenger side front.have someone bump it over with your finger over the plug hole when u feel a big amount of air come out thats the compression stroke not a little amount but a good amount and 0 degrees should be close to the pointer on the balancer.line the balancer to zero degrees...now the the rotor has to be set .dont just slap the dis in there so its pointed to the number 1 spark tower on the cap thats the wrong way.now if u have the motor set at tdc on the compression stroke set at 0degrees your good.if ur not sure u can take the pass side valve cover and make sure the front rockers are all the way up if not then ur off and do it again.ok now set the dis in u want the rotor facing the intake straight back.it wont be perfectly straight back and will close to pointing the ft driver side bolt for the upper intake.now that the rotor is set bolt on the dis clamp not to tight ,u still have to set timing but u dont want the dis to move much when u start the engine .now u can set the dis so the rotor is just under the number 1 spark tower on the cap.check to firing order 2 or three times and make sure u have the right firing order the 302 ho is 13726548 and that is in a counter-clockwise order on the cap.now start and set the timing.put it at 15 and rember that each line 2 degrees. do this to the T and it will be right.
goodluck
