Okay, so I have a 1993 Chevy Cheyenne 3500. Its 4wd, has a 7.4L 454 in it. The engine is blown and I have 1 year to rebuild it. I'm looking for the max horsepower possible for mudding, dragracing, but I also need it street legal? I need performance parts ideas, as I have never rebuilt an engine before. I will have roughly five-ten thousand dollars I can spend on it. Any advice will be greatly appreciated.
