Talk Morgan Forums Morgan Sports Cars Classic Morgans (pre-CX) Reducing Gear Ratio on Diff

I have a John Eales 3.9 in my 1980 +8. Happily revs past 5k. But I don't take it past 5k these days in any gear. Have had it at 5.5k in 5th on a rolling road over 140 mph on the speedo. Chained down and 10 ft from the wall in front!
