Do HVMC's hurt larger CID engines?
Your GIRL has an LS7 Z28?!?
But on a 427, you could prolly do some 2" headers or 17/8" to 2" step. The ones you have now are pretty stout. The HVMV just helps create a dead spot after the point of restriction which should "pull" some exhaust and help flow quite a bit.

Thanks for the info.
Here is the build/dyno/track time thread.

Still, a 427 is a healthy power plant. I think you could run some 2" LT's, but not sure of the gains. Check the Gen IV External Room.
Chick + 427 = win²

Anyway.. how's OP doing with those Kooks LT's?! I may take them off your hands if you wanna get rid of em.
