.. if you can . find a rear end off a spider..78-94? this will have a lsd in the rear.

.wont make your car faster, but it will make your power work better.

.and also.. flush! your brake fluid

( had to rebuild a whole system on my friends 1968 gtjr1300.. the whole system was rusted,

and the rear hose was collapsed.

.. man that was a job)can you do your own work? if so a cam change will work some. but porting the heads will help a lot..
