Not trying to patronize you at all, just offering ways to get the answers you seek. Although the HiPo forum is a good start for "Modified" trucks, you may find more specific answers in the Engine forum for your motor questions or the Driveline forum for things like suspension or tranny work. A lot of forums to go through but that is what makes this site so unique. As you said "No harm done", so jump in the pool and have some fun.
