GEAR CHANGE ?

[Instigator]

I have 26x10 rears, shifting at 6500, 150 shot , running 410's now

i ran it with 150 and never seen the shift light at the big end so i still had room before it ran out

now im going to run a pro systems, 200 shot and im putting a new rear end in it,
should i stay w/ the 410"s ? will the extra 50 horse going to make enough difference to the RPM's to change the gears ?
the car has never been to the track and from what i can tell its crossing the line (street line ) at about 5800
