sup I got a 93 z28 and i have it for about a 2months and now i need a new timing distributor so can someone help me and how much can it be and can i change it myself thanks alot

 

The car uses an unvented Optispark. They runaround $300-$400 depending on the brand. You can get GM, Summit store brand, or MDS. If you change the distributor you should also change the water pump, because if the pump goes bad and wets up the distributor, you will be changing the distributor again.
