I dunno...the 4.6L is a pretty good for efficiency. Good hp/L. You can tell it's struggling a bit though with my 4000lb vic. It gets moving pretty good(police intercepter), but it has to rev up, no bottom end torque. Quite the switch from my inline 6. That was a good read there KULTULZ, I didn't know all the new ford engines shared internals. Reminds me of the chevy small block
Does that mean I could turn my 4.6L into stroker 5.4L?
