Thanks Rumblefish. You have answered plenty of my questions in the past too, thank you! The 360 I'm buying comes with a complete valvetrain for hydralic, so I could go that way too. I just dont know what cam is in it today until I have it apart, or maybe if I can learn to use one of those degree wheels I've read about. Is that possible? it would be awesome if I could use the valvetrain and the Magnum cam from my 273 and still have a great street friendly torque motor. I have also looked at the Hughes Whiplash cam, but it is really expensive.
