GM Opens "Tuner Source"

[RL-2005]

basically would the weight savings of an LSJ compensate for more power and torque (and weight) of the L67

L67 swap is "easier" and well documented (and still keeping it Eaton style)

LSJ will work, can be found with less mileage, and I already know more about the bolt-ons and stuff but it is a rare motor and hasnt officially been done before (a few have tried)

What would you do given those choices and a set budget?
