well my donor 4.0l had the upper intake loosened at one point so that water was able to get into the intake and past the valves in a few cylinders and sit for a year or so.it was already bored .030 so its a parts motor now.
anyway i heard that you coulden't run a fast burn long block in an early(91-94)4.0l truck.ford supposedly says you will melt it down if you do.what from?detonation?if i could get a low mileage 95-2000 long block in my truck it would be easier to find in junkyards.i know the exhaust manifold is different on the new head but can i keep the first gen intake or is it relatively easy to swap to a late model intake(yes i need to change all the sensors too.)?
