Planning on installing 4.10 gears and 28" tall tires. Do you think that too much gear for stock motor KB with 10lbs boost?

Should put me at about 125mph at 6200 rpm at finish line in 4th gear, if I,m calculating correct.

What do you think?

Jack, I am at 15 PSI with the saleen. I run a 28" tire with the 4.10's and go thru the traps around 6700 RPM's.
Mine is an auto, so it is a bit different, but some of our customers running the 4.10's with 28" tires and 5 speeds are crossing around 6200-6400 Depending on how good they hook!
