Depends on alot of stuff as mentioned, but if you're just factoring in loss from the 4L60E, maybe 2mph.

I lost 5mph when I did the swap. The only change was converter and trans. That was with a 3400 Vigilante. I actually went slower too........

With the right stall/gear/tire your ET will improve, even if you lose a few mph.

Back in the day. I went from 117 mph (manual) to 113 mph (auto conversion). Dynoed car after and lost almost 40 wrhp with verter unlocked. Verter locked, I lost 10 over manual tranny. So, 30 loss for verter alone. Car's ET dropped over manual.
