in need of serious help i have a 1979 chevy 350 truck. i replaced the distributor cap, rotar, ignition coil, ignition coil module, starter, and spark plugs any help on his would be amazing im pretty s

So taking it to the shop means more money and you have already thrown lots of parts at it. Probably would have been less money to take it to the shop in the first place. You failed to state what the problem is.

I dont have spark.

I would check for 12 volts at the coil when the ignition switch is turned on.
