I used one of those in my 4 x 4 panel for 18 years.I found the split between 3 and 4 to be to great esp if you are pulling a load I pulled it when i took my detroit out of it. I felt that it was to much trans for a 283. I put a t5 behnd the 283 and if it doesn't work then i will go for an upgraded one or a 700r4 which I have ready to go in. I ran an independent np205 behind it
the shift pattern is also different as when you go from 3rd, you usually go up and to the right for 4th though on these you go to neutral and then drop back down for 4th and then up for 5th
i never had any oroblem with it . it is a good heavy trans. you would never hurt it behind a sb. it has a much bigger input shaft
if you want any measurements give me a holler and I willl get them for you as it is still waiting outside to get shipped
