Re: 4th gen headers in 3rd gen
yes, the ls1 headers bolt right up to my bbc. Why buy 3rd gen when you have the option on 4th gen. There is more technology in the 4th gen headers.

the only headers that will work from a 4th gen are shorties (on lsx swaps). mids and long tubes absolutely will not fit.
