After driving the Cobra for a few hundred miles, I've come to the conclusion that the 3.31 Powerlock diff presently installed is too short for the engine. The engine can give a lot more without compromising acceleration.
I'm looking for longer legs and wish to swap in a 2.87 diff. Unfortunately these appear to be quite rare, and my local Jag breakers have not got one.
I've got a spare 3.07 powerlock and a 3.31 open if anyone is interested?
The existing 3.31 P/L is going in a Dax rolling chasis i'm currently building up.
I am not looking forward to swapping out the diff in a fully built car. Luckily I had the forsight to make a diff bolt access panel in the boot, but it still looks like a bitch to do
