A-833 2.47 1st gear change to 3.09

I took my original A 833 ball and trunnion 3.09 1st gear transmission and converted it to slip yoke using (what I believe was) a '66 trans main shaft and tail housing. It worked. But I will say, when on the track, I hated the 3.09 1st gear. Probably cause I was also running a 4.56 rear end gear. Seemed like a blink after launch I had to shift. At that point I had not even mentally recovered from the launch. FWIW.
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.
