Need some help with high torque 408 build

Sounds like I'd be better off leaving it on the stand and "doing it right the first time."

As I read through everyone's comments it became clear I didn't pick out the right cam! I realized that the cam torque curve I was looking at was for a mild 360, and that a 408 can use a lot more cam and still have a similar torque curve.

Thanks for helping me understand!
