We have built a few engines for boss hoss's, and, they are insane. We have one guy, that we are building a 598 tall deck BBC for one. These are true street cruisers, and, solid roller cams aren't the best choice for them. Besides, The stock 355hp 350's or 502hp 502's will light the tires for as long as you want. One local guy has a 632 engine in one, that makes 830 ish on the motor, and 1100 on the bottle, lol. Thats plain rediculous, but, he is the local dealer for them, and, his bike has got to be outragous.
If you ever imagined riding a a V-8 engine, by itself, thats about as close to it as you can get. They are described as being the biggest speed thrill there possibly is. As totaly over kill as they are, they are still cool
