I have a '88 Firebird with an LB9 roller-cam engine.

At the moment, the car is running with an old ('76) HEI dizzy.

I am looking at a replacement distributor on ebay - made by Wysco, with a '4340 Chromoly Steel bottom Gear, for use with cast and Steel Billet Cams'

ebay item no is 260124601248

And I would like to know if this distributor would be suitable - I know there are issues with drivegear/ roller-camshaft compatability.

As far as I can gather from what I have read, the factory roller-cam in the '88 LB9 is cast iron, so will the dizzy be o.k for use with my engine?

Any suggestions/ help would be greatly appreciated.

Thanks.

 

That auction is for a distributor for Pontiac engines, like in the 1st gen Firebirds and some second gens. Back when Firebirds had pontiac engines and Camaros had chevy engines.
The LB9 is a "chevy" engine.
