[QUOTE=Mark Shead;6258037]Didnt think of that, It would be worth working out the rpm per 1000rpm and see what it is,
For me the tremec on stock final drive and .82 or .83 what ever it is was just about right for a Cossie.
Also look at the speedo drive as one is electric and the other is cable from mem.

23 mph per 1k
About 180 ish
I've got a didgital speedo that runs of the front wheel
So that will save ME, at least the bother of cables.
Good call though for other people wishing to convert to the tko,
