hey guys i have a tired 5.3L with a whipple on it , i was planning on putting in a different motor but i can't decide which one to put in i was thinking about a 6.0 or a z06 motor but still not sure, i would love some suggestions.

 

6.0 for sure, more torque and puts up with boost better ( iron block ). Plus there are just as many parts available as the 5.7L motors.
