Why is engine lacking power? on 1992 Toyota 4Runner

Repaired oil leak in both cams. Timing is right on. Fuel is good. Good fire.

Same thing before the leaks were fixed or is this a new problem?
truck ran fine other than the oil leaks
One of the cams is off a tooth!!! OR the crank.
These vehicles were born gutless.
