Strange headers

[hoghead54]

Has anyone seen or know anything about this type of header? They came on a 6.4 that I bought for my '69 Super bee conversion. I've never seen a collector as long as this one and there is no brand or other I.D. on them. If anyone could she'd some light on them it would be appreciated.

Well, doesn't look like they were on a production car. 6.4, 392 Gen lll? What engine.

6.4 gen III. They were originally on a 6.1 and he picked them up to use on the 392 that I bought. I just haven't seen a header quite like them before.
