will I run out of motor?

Just for an easy example, here is what you would have if you ran a 28" tire, in 3rd gear with a 4L60E @ 7000 RPM. Then the same RPM for a 26" tire.
These numbers are rounded off, so not exact to the tenth.
Here is a link to the calculator I used, you can go put in your own data and see what RPM/MPH you will have with different combos. Hope this helps.

7000 rpm
4.11 rear gear ratio
1.00 trans ratio
142 mph
28" tire dia.

Actually I'm sort of serious about this. Not sure when thngs got turned around, but 4:11 used to be known as a "low" gear ratio, and if you wanted to go to "higher" gears, you got yourself some 3:73s or 3:08s if you wanted to go really "high" geared for the road.
Now, suddenly some folks start to refer to going from numerically higher gears to numerically lower gears as "dropping down".
Actually that statement is logical using strictly the numbers. There is such a thing as tradition though, and traditionally, "low gears" have always been the bigger numbers, e.g., a really low gear ratio is a 4:56.
Just depends on who you have been hanging around with, but from what I can tell, this got turned around by import kids, "tuners" who have no idea what traditional hot rodder lingo is, and couldn't care less.

I think everyone understood what he was trying to say.
Coming from the guy who started the thread by asking if he would "Run out of motor" when the correct phrase would've been run out of gear, I can see why you would say that. No smiley.
Now you know where I'm coming from. And yes, I meant to say gear not motor, you have to keep in mind more than 1/2 the time I'm on ls1tech it's at night time when I have been drinking a **** load of beer.
