Stock .318 upgrade!

I've never had luck with Holley carbs.
Though haven't had one newer than about 35 years old either. I cringed when my kid bought one for a 440 he had a few years ago, but surprisingly that one worked great. I think it was a Street avenger not sure. Those weren't thought of yet when I experimented with them.
I know I won't take another 1850 model Holley for free...
