Sounds good to me. I'd expect a big grin on your face the first time you got WFO. 
In the 1/4-mile, I think you'll gain at least a couple tenths and maybe 1-2 mph in trap speed...

You won't believe it's the same car. You'll swear you just bolted on a SC or something. You should get dangerously close to 13s.
