put in a 4l80e trans----

I had a 1984 Chev 454 with 4:10 gears---ran around 3300 at 70----course with you guys using kilos---your rpm will be less at 70

you can get a trans guy to work on the govner and adjust shift points---sounds like your throttle/trans link is set correctly if it shifts that soon---does it ship hard or smooth??
