Even if your engine is spotless, burns no oil, starts every time, and runs on a teaspoon of gas, you can do better. The world of late-model crate engines has enabled the proletariat to make ludicrous horsepower numbers while maintaining some semblance of driveability and clean air. You've heard of the E-Rod engines from Chevrolet Performance where you can swap in an LS engine with cats and a fuel system that will get you by the smog police. You might have heard of the Coyote engine and Ford Racing's willingness to release the codes for the PCM and now, drum roll please, Mopar has come creaking out of its grave and released a line of Hemi and Viper crate engines that include a radical 426 and a 500-inch V10 that makes more than 640 hp N/A. Furthermore, Mopar has unlocked its computers, so tuners can tweak the products for even more power.
Now that we have the transmission and rearend guys scrambling to the unbreakable, billet input-shaft bin, I am going to suggest that you also look to the aftermarket for subframes and go-fast parts to install said crate engines. Inside this very magazine, you are going to see a bit of that. We have the Coyote swap, where we managed to weld a Heidts engine cradle into a '66 Mustang and plant a Ford Racing Coyote engine with it. It's the first step in a long process to get a late-model modular into an early Mustang, but it's a good start.
General Motors, through the Chevrolet Performance Division, is way ahead of things, as usual. In this magazine, you are going to see an LS3 engine-swapped El Camino with the new Edelbrock E-Force supercharger. It makes a lot of power, so much that we haven't run it on the dyno for fear of destroying the transmission. We added a fuel-pump story to help feed the whole thing and a spotters guide for junkyard and Internet scores.
If racing is what you like, there is the Coyote Stock class run by the NMRA, and several engine-swapped street machines and street/strip cars. So crack a cold one and start planning that winter build. Engine Swaps will show you how.
