You are saying the 5.3 heads outflowed some 5.7 heads when you put bigger valves in? Wow. That is sweet.
I guess I'm just not understanding the reason you would want to go to the car intake. You are just saying because the LS1/6/X intake is far superior to the truck intake? The motor I was looking into is fully complete with all assessories now.
Thanks again
