HemiTronix

That's also a big reason I started my Hemi swap with a carb. I don't care what people tell you, it's CHEAPER to drop a Hemi in with a carb unless you get all the factory wiring and computer with your engine and are willing to cut the harness up (the only electronics I got with my engine were sensors I ended up replacing anyway). I had the Hemi in my car and running for under $5k, engine and machine work included, when I first did the swap, about the same cost I added up to build a stroker smallblock or buy a supercharger kit. Sure you have to buy a new intake and MSD for the ignition (~$1000), but you don't have to mess with your fuel system for injection, you just need an electric carb pump. When I converted over to fuel injection half of the cost was in my fuel system alone.

I'm not saying that I don't like my fuel injection, it's frickin' awesome. But if you have the parts and ability to tune a carb you can do a Hemi swap for a pretty reasonable price. The other reason I like the Hemi over the old engines is the potential of them. Stock heads pretty much outflow some of the best ported smallblock heads out there. Add a cam to a junkyard engine and you've got 400 hp in nothing flat. Go with heads and other bolt ons and you can run 500 all day long and still have the street manners of a grocery getter.
