Alternator pully size

Do most of you with a BBC street/strip motor use a regular size pulley or do you under drive it with a larger one? thanks

Re: Alternator pully size

in my opinion under drive pulleys are for under powered mustangs. I tried a set on a street truck I had with a small block and I hated them so I took them off.
