Keisler SS700 gearbox.

[Donunder]

Thanks to all for your replies.

I've been reading the Kiesler newsletters and reading "between the lines" I've gained the impression that either the SS700 is so popular that Kiesler is having difficulty coping with the demand, or.. they're having supply chain problems of their own making that they're not able to address satisfactorily.

Either way it looks like a long wait before anything I order from them would find its way down under. And -- there's always the niggling feeling that any possible after sales problems could be difficult to resolve from way down here.

So--decision made--I'll go for the TKO 600 with the .82 fifth gear. I feel that with the fairly mild cam in my 454, it would still be grunty enough to cope with a .64 but only for extended highway use at 110 kmh where posted. Autobahns are but a distant dream in Oz so I agree the .82, while working harder, will be more useable more often under varying road and traffic conditions.

Again, thank you everyone for your helpful comments and advice.
