I have a '71 FJ40 that has a chevy 350 in it with a NV4500 5 speed tran. I am in the tear down process but am thinking about putting a new engine in this truck. I am not much of an engine guy so I need advise on what engine to put in it and where to get it. I would prefer not to change the trans. but will have it rebuilt. Anything other information you all have would be appreciated! Thanks
