Toledo 1300 to 1500

[Pearce]

hi what effect will leaving my Toledo 1300 diff while using dolomite 1500 engine and box. Better acceleration or lower engine speed at speed. Cheers Carl

It will be under geared in a word.

The usual diff ratio for 1500's is 3.89 or 3.63.

It will be quite fussy at motorway revs with a 4.11

Is not good for a 1500 to rev high for long periods as the crank throw is long and the bearings marginal.

My Spit 1500 is ok but I avoid cruising at much over 3500 rpm but then I have 3.63 and overdrive so that
gives me an adequate safe cruise.

I ran mine with a 4.11, but overdrive is essential.
If no OD I would be fitting one or a 3.63 diff.
