I recently purchased a 426 magnum stroker kit. It is great. It pulls awesome from down low. The factory fuel injection works good with the computer programming and it sounds great also. The best thing is that if you look under the hood, it all looks stock. I have pulled several heavy trailers with it and it does a great job. Fuel mileage is about the same as the stock engine but power is no comparison. Thanks for all the help. Hughes is awesome. I have included some pics of my truck. Let me know what ya’ll think.
