Yup, the good ol' 1087. I forgot to ad that to the description. Old buddy of mine back in the mid 90s ran low/mid 11s on motor alone at Rockingham, NC with this cam and his 93 Cobra's GT40 heads were ported/polished and his original Cobra intake was extrude honed and shortened. The shortblock was a 306 with hypercraptastic KB pistons. I've had this cam almost a decade and have tried selling it before, but then I keep getting indecisive. Well, now I'm getting out of the hobby for a while so I can get college schooled.
