yes that is right this stuff is very new to me and I would say that I understand some of what is going on the lockup thing I do not understand and I struggle with the number of tire rotations at given engine rpm. I could plug in numbers for ever but if I do not fully understand it the info that gets spit out it may as well be useless or be in jiberishone thing i've observed in this thread is you need to take into account rpm AFTER lockup, this is good for 100-300 rpm drop.
If you think your rpms might be too high for your comfort just remember how much more power it takes to push those taller/wider/heavier tires down the road.
I get trucks in every week with 35s and 3.42s with 4l60s and they have put too big of a cam in and want it tuned. Then complain it doesn't make any more power.
I suggest 4.56s for 35s to get the final ratio back a little better than stock. Got buddys that went from 3.42/35s to 3.90 or 4.10 and 35s and regret it. Eventually they went to 4.56 or 4.88s and finally were happy.
Don't fear the gear.

can you explain what tayto is talking about with the lockup rpm drop and what do the numbers represent in the 1000 to 6500 rpm range on the carts is have post that is what is going over my headMany tires have revolutions per mile included from the tire manufacturer. At 60 mph that would be the tire RPM. Then again, I am not sure why you would need the tire RPM if you put an accurate tire height into a gearing calculator.

Would it not be the other way with the charts regarding lock up. The chart shows rpm for specific gear ratio, which would be with torque converter locked. Before torque converter lock up, rpm wold be higher by a 200-300rpm?
