Looks good!


A vote here for the side oiler!
The diesel engines are too heavy for what you want - and would require too much work in terms of axles/suspension/engine mounts etc.

The 5.4 would be nice, but too much work for what you are going to gain from it.
Either the Boss 429 or the side oiler, and because you have the side oiler sitting there and doing nothing, it might as well be under the hood!
