If he doesn't use it, won't he have to get another ECU or flash that ECU with a model year program that had the cable driven throttle body instead of electronic? I didn't know MSD had come out with a coil but at $75 per I think I'll pass. And as far as the thread for Street & Performance that lilred67 provided, they have some good stuff but a lot of it is a lttle on the high side (price wise). And Rob, like was mentioned, not a super deal but not bad either. I would compare it to buying a crate engine also. Get it and one start saving for one of the new 6L80E's. Throw the Shrifter on there and drive the crap out of it..... Sorry, I get carried away.

No you can reflash the PCM and modify the harness to go to a cable TB. Alot of the hard core vette guys do this. It eliminates alot of computer problems/trouble that comes into play when you get some serious power adders and big cams.
