So this came up for sale on the local CL and I was thinking of picking it up to rebuild and eventually swap into my RRC. The seller doesn’t know how many miles are on it, only that it had bad rod knock.

I’m thinking it would be a fun project to rebuild this thing over the winter. I’ve never done an engine swap or anything like this and I think this would be a relatively cheap way to learn.

I’m worried that I’m gonna get in over my head and end up spending a ton of money on expensive parts then blow them all up the first time I turn the key.

Is there anything I should be looking for when I go see this in person? I’m not sure there’s a way to tell if it’s a 4.0 or a 4.6 and the seller doesn’t know. The plenum is missing as well as the exhaust headers. It looks pretty leaky, but so does my 3.9.
