unfamilia something is wrong with that cam I think its a race only cam and that would mean low torque down low, need re-curved dizzie and bigger 180b style sus and specially high revs!!!!.

Even with a well jetted 32/36 dgv carb you could get 100hp at the engine with a fast road cam 70/37 , high comp a15, extractors, re-curved electronic dizzie and slightly cleaned up head.

The 80/40 cam is quite big if it doesnt have the right juice, air and spark.

Sometime its better to be more conservative with the cam choice like boof has proven. It all depends what you have in mind.
