[Tigers] Re speedo gear- Number of teeth?

[Ron Fraser]

Tony
    This is where you need to put together a nice little calculator sheet to
determine the right cable gear.

980

16 / 6

907.4


980 is the # of revs the speedo is looking for per mile/ listed on the face
of the speedo.
16 = driven speedo gear
6 = the gear in the transmission
907.4 = tire revs per mile with 2.88 gears

I thought I had a calculator spread sheet for this but can't find it right
now.
Maybe it is on one of the web sites that sells gears.
I believe you would need more teeth on the gear.

Here is some gear information:

Drive gear in trans         original #          B7C-17285-A      6T

                                    6T                    E3ZZ-17285-B

                                    7T                    E3ZZ-17285-A





Cable gears (driven gear);



15T      C3OZ-17271-A

16T      C1DD-17271-A

17T      C2DZ-17271-G           C3DZ-17271-B

18T      C0DD-17271-B

19T      C0DD-17271-C          C4DZ-17271-A

20T      C1DD-17271-A          C2DZ-17271-H

21T      C4OZ-17271-A

Ron or anyone. If 15 tooth was for a stock setup. Does a person running a
331 rearend need more teeth or less. I realize the 15 tooth isnt available
and Im not sure what gear is needed for which rearend  or what 5th gear if
applicable.
