Anyone familiar with this author's preferences will of course know that the lack of any of GM's GenIV pushrod V8s is slightly upsetting, and once again all of the heavy-duty light-truck diesels got snubbed as well. Ford's supercharged 5.4L would, in our opinion, be a shoe-in based upon the big bruiser's industry-leading HP-per-dollar ratio. And on the other end of the practicality spectrum, where are the fuel-sipping engines? These are minor gripes, though; Ward's put together a solid list of engines that we'd certainly be happy to thrash.
