[Spridgets] More highway speed for a bugeye?

[Rick Fisk]

I don't remember the exact changeover, but it seems like it was '68 or '69 when they switched to the 3.9.

As Derf said you want one that has 10/39 on the top of the differential case but check yours first to see which you have now!  There were at least 3 available. Early cars were 4.22 to 1,  then there is 3.9 to 1 and the shorter 4.22 to 1.  The 4.22 is great for autocross -  the taller geared 3.77 for highway use.  As was noted, the taller gears are getting hard to find and usually demand a suitable hunk of cash.
