4-Speed Swap Donar Car Question

FYI
You know;a hi-stall automatic behaves like a 4 to 4.5 speed right? add a loc-up and it's a 5+ speed.
First the A727/A904 with 2.45/1.45/1.00 and 5.13s. The road gears are
12.57-7.44-5.13...... And the Commando 3.09-1.92-1.40-1.00 with 3.91s
12.08-7.51-5.47-3.91..... so it looks like the 4-speed is the better choice.
But wait! the convertor has an internal multiplier that can exceed 1.8 at zero mph,which automatically and rapidly decays to, in the range of 1.10 to 1.05 at WOT. So then on the street, she wouldn't need the 5.13s. Lets try 3.23s /A998loc-up /and 1.80 to 1.08@WOT and I get;
14.24-8.55-5.06-3.49-3.23 so there you have 5 ratios. and the Commando playing catch-up is
10.97-6.82-4.97-3.55

But wait! there is another option. the A999loc-up with ratios of 2.74-1.54-1.00..With the lower gears now you can use 2.94s, and I get;
14.50-8.7-4.89-3.18-2.94..... compared to the M/T at
9.98-6.20-4.52-3.23

The A904 loc-up splits are; .60-.59-.69-.925
The A999 splits above are; .60-.56-.65-.925
The Commando splits are; .62-.73-.71
Remember this when you start your engine build and cam selection; the A998/999 will need a slightly different cam.

Jus saying
