Heres my delema, im looking for a set up that will get my power to max out at about 6500 rpms. If i run a hotcam what will the specs be on it with 1.7 roller rockers on it? And can a 23 degree head make good valve train geometry? On the other hand would i be better off running a 233/242 duration @ .050", .569"/.576" lift with a 114 lsa and use 1.5 rollers with it? Its gonna be goin on a fully forged light weight 355 with ported stock heads and a ocassional 150 wet shot. Any ideas?
