[QUOTE="gimmie11s, post: 16618964, member: 17953"] Interesting. I didnt think a lot would be gained due to the amazing head design from factory. The parts only, with minimal tuning changes yielded a 13 hp gain on his first pull. After TONS of runs and tuning changes they ended at 457 whp, which represents a 49 hp gain. 457whp out of a heads/cam swapped 7.3l motor is, well, ... I guess I'd be pissed. Sure does sound good though!..... just like an LS powered GM. [/QUOTE]
