3.73 or 4.10 with my setup

I am in the middle of a a4 to m6 swap and was wondering if it would be worth it to go My car has long tubes headers, cold air, drag radials, 100 shot, and some suspension. I WILL ALSO BE DOING A GM847 CAM SWAP AS WELL. What do you guys think will it make that much more of a difference. And how much faster. Thanks

with an M6, id do 4.10's... I really really liked mine. And you can do 100MPH at under 3k rpms.

So you still get good gas mileage.

I got around 16-18 mpg driving it fairly hard. 18-20 if i was easy.

The run below was the best run of that day, we had the rev limiter set at 6200 because the engine had 125,000 miles on it, and I drove it through the traps bouncing off the rev limiter, as I didn't want to have to use 5th gear. I'm the one in the left lane with the .012 reaction time. Yes, I got lucky... lol Bob
