Jeremy, The 4,200 discussed here is a DOHC inline 6. It would be a very good choice for your project and you will get lots of advise here. You will need to make a lot of what it takes to make it work but when done your truck will be dependable and unique. It will not be something your mechanic has done before. I hope you are a successful artist as it will not be the least expensive way to go, but by far cooler than a 350/you name it auto combo. We are "INLINERS" here, don't expect much excitement over any "V" type engine. Get a 4.2 and join our club. \:\)
