I have a 700/r4 behind a 408 smallblock. The engine is probably in the 480 to 500hp range. The pair have been in my truck for probably 15000 miles now and the engine could use a freshioning up but the transmission has held up surprisingly well. It has the monster in a box trans kit in it and a corvette servo with a 2800ish stall lock up converter. I had the guy who built the trans set up the tv cable and it shifts great. As most have said on here they are weak in stock form but are pretty good when built and set up right. As for your shift indicator all of the venders carry overdrive indicator lenses to address that minor issue.
