cam swap question
OK i have a 402 with a TFS head in a 98 Camaro stock weight 6 speed 3:73 rear the cam i have is to small and one of them cheater ford lobs which i don't really like that. the car is more of a cruse but a little kick so i was toying with idea but what i want to do is put a 240/244 with a 115 or116 LCA in it now i rather have better spring life and less checking so what would be the HP difference between a xtream RPM cam compared to a XER cam which is kinda hard on the valves and springs opinions needed guys that have shops and had swap cams like this and saw numbers would be great to hear what you found

ya i really do not want to run a XER lob i just really want to know how much better dose the valve springs hold up some one said the extreme RPM would loose 8hp in the mid rang but pick up more up top 8 to 10hp IM believing
