john46, that's what I have and it works quite well. There's plenty of 1st gear pull off the line (sounds like it's a drag racer - nope) and I shift into OD at around 45 mph the same speed a 4L60E locks up. Most here will say a 3:08 is too tall and a lot of that will depend on your tire size too but I can cruise on level ground and even slight hills at 55 or 60 without lugging the 235 at all, it's no big deal to drop it back into 4th if you need more grunt to pull a steep hill.
