Re: 300 into a newer truck?

IMO the only time this swap would be worth it would be if you have a truck with one of the early modulars that used the SBF bell housing and the engine is bad and you have a 300 lying around (which most of us probably do). Anything else is too much work for no gain. I would like to see this done but...

It shouldn't be hard at all to bend a tube/pipe into a hoop so you can support the hood latch while still having a big rectangular space for an intercooler.

With the belt routing pictured you should be able to swap to a serpentine belt setup with nothing but new pulleys and a DIY bracket for the tensioner. That's what I would do. It gets you a better belt profile and more wrap on every pulley. You should already have the alternator pulley lying around.
