I had a very good 2Ltr engine (Vulcan head) and it made almost 190 Bhp with the RL31 but it blocked the rev capacity like a hammer. The same engine made 193 Bhp with HT1e
The engine the RL31 cam came from (also Pinto but 2,1 Ltr and IDF carbs) hardly made 150 Bhp. So as you can see, the cam is not the only part to make power.
