I have the same 3.09 1st gear a833 od with a 3.55 in the rear and hate it too because of the "blink" after launching due to my engine tach's out to 4grand and I have to shift. That 340 would do well with the 3.09 , as it probably can go another 1500 rpms and has a lot more balls than my slant. I say "go-fish" should get a trans with the gearing that you want. That way you have 2 a833's. All kinds of advice on this channel.
