You are quoting the A833 o/d box. It has ratios of 3.09-1.67-1.00-.71o/d, splits of 54-60-.71
And yes it is terrible for a performance street sbm with anything more than a stock teener cam. I ran that ratio with a GearVendor's splitter behind it. The new ratios where 3.09-2.41-1.67-1.30-1.00-.78-.55 with splits of .78-.69-.78-.77-.78-.71 Saweeeet.(GV ratios and splits in red)This was awesome with a small cam, keeping the engine on the pipe from the get go to gone! But it wasn't that streetable. With 4.30s first was all but useless,The final drive of 2.37 was nice. 3.55s made streetability ok. But I just got tired of splitting gears all the time, cuz the splits in the main box were just not street friendly, with even the 223* cam I had in it at the time..The 3.09 box solved all that. I still run the GV behind it, to turn the 3.55s to2.77s for the hi-way. 3.09-1.92-1.40-1.09-.78 with splits of .62-.73-.78-.71. nice progressively decreasing splits.That's the way;unhuh,unhuh.
But Ima still digging the close ratio NV above.I wonder how long it would endure 400 ftlbs?
