If money is not an issue look into the weisco/K1 Technology 351 short block. It will give you 600+ N/A whp no problem and is capable of handling 2000hp with forced induction. They take the coyote motor sleeve, bore and stoke it to a true 351ci and the coyote heads and intake will bolt right up to it they will need port and polished for proper flow. I think the engine build not including port, polish and install is around $15,000 add all supporting features and install your looking at close to $20,000. After it is all done. When you open the hood it will look like any other coyote 5.0. Except you will have a 5.8L 351ci!!! Talk about the ultimate sleeper. Here is the article.
