Selling Corvettes & their Parts
If you want to auction your car or parts on eBay, then post a link to the auction and people interested can get the details on that site. If you have a “buy it now” price on your eBay auction, you may post that with your eBay link.
We allow sales at Corvetteforum, but not auctions, so we want to avoid co-mingling the Forum sale and eBay auction of the same car or parts.

I utilized a L76 intake so I could use the Ls2 throttle body,Also I utilized Yella Terra 1.8 shaft mount LS3 roller rockers(could have got 8 stock LS3 rockers as half are offset).
