That's a riot!
On a more serious matter, a knowledgable customer of mine said it sounded like retarded timing. I did a tune up after getting the car last summer, I was curious if there is a wrong way to put the Optispark back in? It sat flat with the block and felt like it went it smoothly.

See. There ya go. Its getting bad evaporations because its flow is purged. Thus causing trouble code 0497. That's why your car sounds like a sick small block pretending to be a healthy big block. Lol. Just kidding. Probably just a grounded plug wire in all honesty. Any of them touching exhast pipe?
Agreeing with everybody else here, spark plug wires burned and/or cross firing. If you swap wires 4 & 6 it will run exactly like that-ask me how I know.
If that's not it:
The LT1 PCM may have codes in it without illuminating the CES light. Have it scanned with a tech tool.

Alright, I'll just do a tune-up then. Thorough one at that. I used some protectant wire wrap with the plugs that are close to headers so that shouldnt be a problem but there is only one way to find out....
