watched the show Christmas eve, featured the 'small block screamers'.
when they did the hipo, they said it was equipped with a 480CFM Holley carb (the car in the pic was a Shelby, a little mixed info?). A while back, they talked about the 'Y-block' 390. I wonder if they get the Chevy info wrong.
Anyway, that 480 number has been around for ever. I long ago read that a 4v was a 470, the hipo a 480. Where did those numbers come from?
