My 67 peaked out at about 115 mph, dead stock, 4.22 gears, down hill with
the wind.
No other *stock* Sprite or Midget that I have driven as ever made it past
95mph. The 67s were the fasted of the bunch.
Having a 4.22 diff with a 1275 and a 5 speed, I am considering swapping
diffs to a 3.9. 1st is quite low in the 5 speed.
I already run a 3.7 diff in my other Bugeye with a 1275 and can cruise the
left lane at 80 mph all day. The 5 speed is about the same with a 4.22
diff. I can not give rpms because all my tachs are off just a wee bit. I
did try the electronic gismo swap that I read about on the Healey list but
that just cooked the tach. So I use the original electronics and live with
wrong readings.
