    Hi All,
    I found the build sheet as I was removing the interior of the Wildcat and had a question.
    Is it possible to find out what gearing is in the posi as it came with G50 Trailer towing opt and G80 Pos trac diff, or do I still have to crawl under the car and check the markings on the diff? I'm thinking with the trailer package, there may be only one gear set available.

    Thanks in advance, Gary

    The car is getting a bored 455 with Alu heads with around 500+ hp. will the 3.42's be good for the street? I don't plan to run a 4,200 lb car at the strip. Well, maybe once;)

    Depends on whether you mind 2700 RPM at 60 MPH?

    Well, that may make the choice easier. The 3.07's will stay for now. Thanks for the feedback!

    You have the big 9 3/8” rear, no new gears are made for the rear, and 3.42’s are like hens teeth. So, no, you don’t have much of a choice.
