how hard is it to change cams in the 144-200's? I found a cam from crane for my 200 and I can use it with my stock compression and it runs from 1,500 RPM so it is streetable, I plugged this into Dyno 2000 and got 150 HP, then I hit to retard timing 2* and put in small tube headders with mufflers and it hit 180, seems this would be a lot less complex to achive the same hp, than running a turbo, and without the lag of a turbo.
