Long tube headers for 63-72???

[68 TT]

Or if you are on a budget you can buy a set of big block truck headers from Summit designed for the 68-72 and modify them with a set of GM LSx header flanges.

Throw in a couple 1-3/4" mandrel bends and you are still under $150 for a set of headers.

This is a popular thing to do with the third gen F-body guys since their options are limited.

Yeah, thats what I did with my OBS truck a couple years ago before there were commercially available Gen3 headers available to fit it.
