How many revolutions to the Km in an HJ Monaro speedo?
Will help me to figure out the drive / driven gears for diff / tyre combo.
cheers

You can work it out yourself quite easily using factory tyre and diff data and drive and driven gear combos. If you don't have the data I can probably look it up for you in the parts catalogues.

I would have, but the listings I have found give useful info like "3.36:1 diff ratio with QFX, YFS tyre options."
I haven't found the tyre options to calculate the diameter of the wheels

I have a tacho (HJ Monaro), so know the RPM I am doing at 100kph.
What I dont know is:-
a) how many RPM the speedo should be doing at that speed
b) how many revolutions to the km in a Monaro 220kph speedo (from which that can be deduced), or

The early HQ parts manual gives you tyre sizes rather than options. Plus the options list in the front of the HZ parts catalogue illustration section decodes the tyre codes for you. Just search google for the old tyre size measurements eg FR78S14 |
