Man I love all the detail in your write ups. I am not nit picking I am a newb so I have to ask, you are going with a more aggressive cam yet you are not upgrading the springs, or are you?I also wanted to go ahead and change the cam while the motor was on the stand.... In the end, I decided to stick with the thumpr cam... i ordered matching comp cams pushrods, lifters, and timing chains.
