A well built 4l60e should handle your mild 5.3 all day long. The th400 sucks up more hp.+ the 4l60e gives you better acceleration with its 3.06 low gear ratio and the advantage of lower cruising rpms thereby added fuel economy.

i do have a 400 sitting around but the condition is unknown so a rebuild would be a must, the car will be street driven more than anything i just want something to putt around with in the summer. it will be going behing a lm7
Overdrive will help a lot. The only reason to go TH400 is if you're trying to save money or require no electronics. Otherwise the 60 would be my choice.
FWIW the TH400 has no kick down cable or TV cable. It has a kick down switch that needs a signal for WOT and a vacuum source. Those two along with a built-in governor dictate when it will shift.

For a car that you plan on driving a lot, you made the right choice. The only reason to go with the th400 would be if you planned on spending a lot of time at the track.
