I wanted to see if you all just deal with it or have changed the trans to something newer. Thanks for letting me pick your brains.

Try an overdrive transmission like the 2004R or 700R4. I use a built turbo 400 backed by a Gear Vendors overdrive which gives about the same final drive ratio as the 700R4 but will take the torque of my big block which the 700R4 will not.
