Hypothetical - Cheap 360 Magnum Rebuild

Dont put a high volume pump in it, use a good brand of stock pump and you will have 20 at idle and 50 above 1500. A LA 360 crank is the same as the 5.9 magnum crank...
There is a better cam grind out there, more on intake and less on exhaust.
If you put it back together with a good cam you will have 300-325 HP.
