mph to low maybe wrong gears?

I see on a previous post you have 29.5x11.5x15.....that and a 4.30 should work great for a BB...

you should be at least 117-118 mph,,,,,,

I run 122-123 MPH with 29.5X11.5X15 W hoosiers.430 gears crossing at 6200 RPM.
That is at 4000' so ET's are 11:20's-11:30's.@ sea level 125MPH 10:87-10:95. My converter is a JW (glide)stalls at 5500 so I know there is slippage
I ran the same combo with 4:89 gears, but was out of wind by the finish line @ 7200. I have the rods ect. to take it, but no HP at that RPM.I didn't want to run it that hard.
I just switched to 4:57's (ford 9") so we will see this weekend. I should cross @ 6600. I wanted a lower gears because of the 'glides 1st gear (like leaving in 2nd)
