Does anyone know of a TB that is compatible with a 91 Camaro RS LO3? I've checked Holley's 670 cfm TB, but they say it's for 87-89, and I've heard a lot of people say that they suck anyway. Any help would be greatly appreciated.

 

They suck? Wow, you have been talking to the wrong people!
Maybe walking through some threads here will give you more of an idea.

 

the holley unit is perfectly fine. anyone who thinks other wise is not informed. the reason they say it is different is because gm changed teh style of the throttle position sensor they were using. all you have to do is go to a junk yard and get one of the old style connectors thta has the 3 wires in a row instead of the little round connector they used on the later cars, just cut the connector off so it has some wire to work with and solder the new one on. they didn't even change teh wires, so all you have to do is match up the colors to reconnect it.

later
