V8 swap or 4.0 OHV heads?
I was looking into adding a much needed horsepower boost to my 2000 4.0. I have found very few ways to get serious horsepower out of one of these engines.
I was debating swapping in a 5.0 (205hp) from an explorer or getting Morana stage 3 heads for my 4.0 (160hp+ 30hp + bolt-ons already in place).
Swapping heads would be easier and my bolt-on applications would be able to live up to their potential with better flowing heads.
The 5.0 has way better horsepower and torque out of the box, but may be a bear to install.. Along with hidden costs that go into any customized job.
Both ideas are expensive, heads being slightly cheaper.. in time and money spent.
Any opinion on the matter?
