I have two friends that went to 7" converters in their SS/GT carbureted cars. Already fast, sorted out cars. Both picked up everywhere. I decided I had to have one of those!
Two 7" iterations later, my 8" ATI was still quicker and faster. Depends on the combo, like many other things. Or, I'm doing something very wrong. A strong possibility. LOL
