Man you guys dug this thread up. But anyways my install ran $250. Overall the best speed mod I've done so far. After I get my spydershaft and trutrac put in I'm hoping to cut a mid to high 12 sec E/T.

If anyone with 4:10's could comment on the difference in MPG they saw from 3:55's to 4:10's that would be nice. I too am considering it but drive approximately 50 miles round trip a day. I have read they do great on the ET at the track just wondering what you guys have seen.

I lost1 maybe2 mpg on the hwy. City driving isnt any different from what I've noticed. But I do %90 hwy driving. Not to bad.

But I hear a good tune and such could net you that back in the end so......it "might" be a wash. I do about 90% interstate.

Any idea of the ET differences between the 4.10s and the 3.73's.
