Thanks doorracer, I was curious about the polishing job it had on it not the porting end of it. I understand the porting part and I thought I understood polishing but I still have lots to learn. several people have told me that a mirror polishing job like the one on this intake would suit alcohol better than gas. why I don't know. they said it was because gas needed a more coarse intake so it would have more time to atomize. Still I don't know
Just asking
