They were sup to be level 2 builds. New tqconverter, 2200 stall, can not vouch for or againt the internials. The ori in the car went 110 thou with out any problems, but stock was 300 hp. When we overhauled the engine it dyno'ed at 420 at the crank had the trans overhauled at that time. I'm not nocking the 700, its very possable we made a mistake, or the trans shop did. I personally did not look in side the trans. just passing on my exp with them.
