OMG your killing me here TAZ
Low miles I haven't changed the rear end yet,but I was hoping to go with a 3.73 for street performance.
If you replace a 350TH with a 200R4 ,I read that a 3.73 rear end gear would be more like a 4.10 beacuse of the 2.74 first gear compared to a 350TH .
So I am thinking maybe a Guy could go with a little taller dif is all .
But I was hoping you were lower in rpm on the highway ,although 2200 rpm is probably a good rpm to be at on the highway anyways with a 400 .
I wonder how a stroked 400 would pull with an OD . Maybe run fine under 2000 rpm on the hwy?
