LS6 Intake

LS6 Intake
I'm doing a heads/cam swap (TEA stage 1/Texas Speed 224R 114LSA) here in the next few weeks on my 98 C5. Is the 300.00+ investment for a used LS6 manifold worth the HP gain over the LS1 intake?

From what steve wiliams said, not only is there a power advantadge, but it flows more at a higher rpm, where the factory ls1 (egr) intake typically dies above 5k RPM

25 HP might be a little too optimistic for the LS6 intake.... 17 -18 HP might be a bit more realistic. It is worth the money. Your heads will produce much more HP/TQ with the LS6 over the LS1 intake. It was the first mod on my car. JRP (world famous stickie writer) did a install and a dyno test after his install and those were his numbers.
