how much would it cost to have the manifold replaced on a 94 f250 4x4 hd w/auto transmission, 351 cleaveland engine- also what are the steps to doing it yourself? any special tools required?

 

really a 351 C. in a 1994 i bet it is a 351 W and they r easy to do

 

For a price quote on the job, you need to talk to whoever will be doing the work.

For doing it yourself, let the engine cool down, and spray the bolts/studs with PB blaster a day before. It doesn't hurt to repeat a couple hours before hand. If the old bolts give you any difficulty coming out, then try wiggling them back and forth. The worst case scenario is that they will break.

 

And then the real fun starts!!!

 

To pay someone to do the job you are looking at at least 100 for the manifold(list price) and at least 2 hours x their labor rate
