Excuse my ignorance. Can you elaborate what exactly a 3/4 race cam is? Manufacturer/part number? Would be super interested in seeing the cam specs.

Full race = 1 (4/4)
3/4 race = 3/4
Some call it a stage III

To guess hp off of idle lope is impossible.

actually I think that is from the '50's. did have a guy at a car show ask me once if my engine had a 3/4 cam, I said "no, I put the whole cam in there". he did not seem amused.
