No, I don't think Reg would let you know the finer points of the ratio's either, he'd be effectively doing himself out of business.

BigJase, heaps of companies can cut gears to the spec's you want but it's getting the "spec's" and then you have the issue the "one off" cuts are usually costly, you could do a big run of them and plan to sell them off, but thats risky and you'd have to finance it up front.

Quite frankly, I think 2000 to 2500 for a gear box is good buying, you'll save yourself a lot of time & hassle and you should get something that works.

I have two gears boxes -
1 is described as a "race" box and the gears are very close together and 1st is very tall i.e. its really hard to get my car off the line quickly even with my 4.875, but once you up and running its magic, the car is always in the peek of the power band.
the other box is described as a "rally" box, the gears are close but not as close as the race box.
A friend of mine used my race box once in his sunny rally car, and he didn't want to give it back he said it was so much better than his rally close ratio, but he did have a very peekie motor.

I have a lot to do with Dave Strong, the first thing he does when building a car is a good gearbox and diff, the biggest gains are often here and work out the cheapest in the long run, i.e. pay for good stuff and it last's for ever and works!

well thats my 2 cents worth anyway.
