whats it like to drive a 6-71?

You will have stupid power if you put the right cam in it . 110-114 c/l .
I have a 493 stroker with a Hampton 14-71. My cam is ground on a 114 c/l.

Check Don Hampton . He's a great guy & wicked smart. he will even tell you how to set up your carbs .
Have fun with it & you will love the wicked response & acceleration .
