I know that Jasper remans have a good warrenty and all, but the engines they sell are not all they are cracked up to be. I am an assistant service manager at a local Ford dealership. One of the techs' friends has a 91 X with a two year old Jasper rebuild in it. The engine is leaking out of every gasket it has, and the shop that installed it went out of business, so no warrenty for him.:thumbdwn: From what I have seen of Jasper rebuilds, they tend to use the cheapest parts they can to rebuild engines, i.e., gaskets, lifters, pushrods, etc. The engine I am talking about has about 30K on it and it already is starting to lose a lifter on the #4 and #5 cylinder. Also, be careful about the shop you choose to have the engine installed. The shop that installed the aforementioned engine did not properly prep the exhaust manifolds either, and put cheap gaskets on that are leaking so bad it is hard to stand next to the truck without getting dizzy. The tech is going to replace the valve cover gaskets and properly prep/check the manifolds to make sure they can be used without gaskets like they came from the factory, in an attempt to keep the truck going for a little while longer. Basically though, it needs a new engine again. Good luck on the engine though. If you manage to find a good one(used or reman) these things can run for well over 200K with proper maintanance.
