427RStangg wants to know: “In my s/c Roush, what gear ratio would you recommend? I have friends who say that 4.10 gears are way too steep for my car? It’s a manual.”
When choosing aftermarket Mustang gears (or any aftermarket mod), it’s important to consider what type of driving you do/want to do with the car, how much power you currently make, and how much power you intend to make.
Aftermarket rear-end gears are designed to get you off the line faster, so you’re going to burn through first gear (and second… and third…) much more quickly than with your stock gears. This isn’t as much of a hassle with an automatic transmission because you aren’t the one shifting, but if your Mustang is a stick and you do any kind of driving in a city or heavy traffic, you’d be wise to avoid the steeper ratios. Considering your pony is already super charged, I would have to side with your friends and recommend the 3.73 gears; they’ll give you the extra kick off the line that you want without making driving a chore.
When installing aftermarket gears, it’s always a good idea to get a bearing kit and replace the shims, bearings, and other items that wear out over time. This will complete your rear-end rebuild and make sure you keep that rubber burning for a long time.

Earlier this week, we had the pleasure of hosting our smokin’ hot AmericanMuscle 2011 calendar shoot (featuring the AM girls) right outside my office door! The warehouse doors were plastered with warnings: “Photo Shoot In Progress – Do Not Disturb!” Yeah… right…! As many of our Facebook fans know, we’ve been giving a behind-the-scenes look at the daily happenings at our headquarters. However, when I put my job on the line and leaked THIS photo of one of the sizzling hot models, here is what our female Facebook friends had to say:
Does your Mustang put down over 800 horsepower to the wheels? Can it run 9′s on drag radials and stop at the drive-thru for dinner on the way home? AmericanMuscle and 5.0 Mustang and Super Fords Magazine have teamed up to find the fastest and baddest TRULY streetable Mustangs in the world! Are you ready to throw down?
From time to time, someone will ask us “Why does my car put out 290 horsepower on the dyno if it was rated at 300 horsepower stock?” Dyno results can be confusing for anyone who hasn’t read up on the topic. How can the same car put down different numbers just because the dyno manufacturer isn’t the same? These answers are simple much easier to understand if you know how a dyno calculates or measures horsepower and torque.
