As you can see by my screen name, I'm going to ask some questions that seem stupid to you guys. I thought 351w engines (5.8L) were basicly the same as 302/5.0L externally. Meaning that a 5.8 will bolt up in place of a 5.0. Is this correct or am I way wrong here? I would think the cubic inches would make a big difference. But it seems that there aren't that many guys doing it. That's the question, is it an easy swap or not?

different block size. The 351 has a 9.5" deck height, compared to the 5.0's deck height of 8.2".

yes, for the most part. however the 351 has a tALLER DECK HEIGHT ( sorry, caps) which requires a different lower intake manifold and such. im dure more people will chime in, but thats just a little of what know

well ill put it this way it will bolt in, the whole job is a bolt in procedure, you need to get a different lower intake, 351 swap headers, possibly bigger injectors, I think you have to use different engine mounts, im not sure, but thats the meat of it right there, just some other little things and your good.

Don't forget a different hood. A 5.8 will require at least a 2" cowl hood to be able to close.
