The origional poster was asking about INLINE 6 cylinders in SUPER STOCK. I think the biggest issue would be the small 1 barrel carb that would be required that most inlines used. I wonder how a Pontiac SOHC 6 with the factory Q Jet would work in something like a 67 Firebird or LeMans. Or maybe one of the old Hyper Pack MoPar slant 6s, although both likely have too high a factory HP rating.
