They did not make a 8 cylinder Vortec motor until 1996. So what is it you have? I see you mention a TBI, is that what you have?

Sounds like you don’t have a Vortec engine unless it been replaced, Eather way back fire as you decribe is caused by the timing being off possible you moved it when replacing cap and router. Did you replace roder Check timing and make sure got cap on securely. One more possibility and very likely you have crossed a couple plug wires easy to do . Tag each end of plug wires with a small piece of tape and number them probley find 2 wires are on wrong plug . 1357-2468 firing order v-8 Chevy numerals are on cap end.
