Low Dollar 318 Grand Finale Exit !!

I have an open 3.55 center section to put in it, but I'd like a sure grip, maybe 4.10's. I will borrow the drag radials from the other Duster.
The way that sounds leaving now, I'd think 4.10 would be minimum. I "bet" it would even respond to 4.30s or even 4.56s. It sounds really good.
