When I was looking for a Fox, I drove two with 3.73s (one was bolt ons + cam, the other was just bolt ons) and I can say that both were a blast to drive. This isn't as relevant because of the different drivetrain but I had 3.73s in my LS1 fbody years ago and loved them too.
My fox has the stock 2.73s and I spend way too much time thinking of getting 3.73s.....eventually.
3.73:1 is my favorite gear ratio. Cruising at 72mph in my 89 I got 26mpg. It was a blast to drive with z spec transmission and 26 inch tires. 3.55:1 are decent and will help with that 5th gear reach for another gear....that doesn't exist.
Most 6 speeds are on the market are BS. It's actually 5 speeds with a spare 5th gear. The change in ratio between 5th and 6th is barely noticeable.
True...very true. I was talking about when you have 3.73:1 gears and trying to cruise. The rpms are so high that it makes you want another gear to bring the rpms down. Most configurations of 6 speeds are just BS. The magnum t56 6th gear is .50...the cobra z spec is .62. I'd say that's an improvement....small but improved. That's almost the difference between the 3.55 and a 3.73.
Mine has 3.90's and it seems to be a nice compromise between acceleration / highway revs. A bit high, but tolerable.
Just curious why this isn't a popular choice??
