Okay so I consider myself still a newbie when it comes to the hotrodding world we all love so I am coming to you for input. My buddy has a foxbody that he road races and is looking for more power. His dad told him that he can get a 331ci $700 eagle rotating assembly and put it in a "boss" 302 block with some certain head and it will make 450hp (which I could understand) but he then said and spin it 9-10k rpm all day long with no problems.... I feel as though this is..... well seems like rather out of reach assuming its probably a cast crank with steel i beam rods and hypereutectic pistons but hey I could be wrong... it has happened before and im sure its not the last. Can someone with more experience as me chime in on this? I just wanna know how far off the road I am or am not.
