It was a low production rag, I don't recall the name (and in a quich search I didn't find it).
I remember it crediting some of the hardware to one of the Hambers (specifically a HEI module mount that looked like half a ribbed aluminum ignition coil cover).
Might'a been GMC Bubba's stuff, might not (not that good a memory).
If I run across it any time soon, I'll post what mag it was.
