An engine swap is the bedrock of hotrodding. It’s been that way ever since someone first dropped a Flathead Ford V8 onto a spindly Model T frame. That paved the way for folks to stuff all manner of massive powerplants into absurdly small engine bays.

…The results, of course, are all sorts of awesome.

So we came up with a list of our Top 10 Favorite Engine Swaps. Take a look at the list, click the headlines for more details, and let us know what you think in the comments section below.
