Were the rollers illegal?

Oh yes, very. Especially NASCAR who wants to make everything same same. Using those bearings cut down on frictional losses and you could use a smaller oil pump that took much less parasitic power from the engine. Might be good for 5 mph compared to a legal engine, and in NASCAR that's huge. NHRA it would be OK in modified classes but very illegal in stock, SS, even FX classes.
