surprise surprise the head gasket on my 94 3.8 just went. Now the question is, is it worth it to replace the head gaskets and is this a job that I could do on my own? or would it be better to just swap the engine out. I have a little over a grand in savings and this is my only car, any suggestions?

will a 5.0 mount onto the 3.8 tranny?
can my 3.8 drive train handle a 5.0?
what all do i need to swap out?
I have found a 5.0 that would come with everything including ECU and harness would this work with my tranny, drive train axle?
