Very little. But it’s more of the lobe and style cam that is going to show more of a difference. I’d follow 33Imp’s advice. Power wise, there similar with the roller making more power IMO.
Diving deeper into this is just trying to split a hair.
Solid grind for the street, the roller for the track.
The roller’s description even says “Drag Race” while the Hughes description says street strip/race. The roller will be a more aggressive cam. The Hughes cam is stout for sure. I’d run that with 1.6 rockers on the street.
