We put a BBK 80mm on a 382 Stoker/Procharged vette and it lost horsepower on the dyno and never truly idled right. We had Mark Shaner port in to around an 82mm, and gained, but still lost compared to before.
Then we had him port and polish a stock one, and it made more than stock and the car idled right.
Stay away from the 80's, they are junk.
just my .02
