Gene I run a 3.9 ratio rear end with my Shorrock supercharger .It was recommended to me by Brown & Gammons This ratio is fine for my driving -gentle hills but fairly long fast highways. It means I can cruise along the highways at 60/65 mph with revs at 3000/3500 -less stress on the motor! However if one does a lot of hilly driving I suspect a lower ratio would be better. I have no problems keeping up with modern traffic around town or on the highway even occasional motorway driving is quite relaxed Paul TC3348 Sunny Hertfordshire UK

Hi Gene and Paul, I run a 4.55 diff in my TC road car. The car is not supercharged but has 9.0 C/R, +0.080" bore, TF valves, lightened flywheel, Crane road cam. I find the 4.55 diff just about right with this engine. So I think wirh a supercharged engine a 4.22 Sprite diff would be just fine and a good compromise between flat cruising and reasonable acceleration. I do not have any Morris 10 spline axles in stock now. However a new batch of axles is in the works and so will have them in about a month. Anybody wanting 10 inner spline axle shafts to suit Morris/Sprite/MG Midget differentials and TA/TB/TC tapered wire wheel hubs please let me know off list.
