Josh,

 

I am looking to wake up my 99 Suburban with the 5.7 also. Have you tried any of these suggestions yet?

 

The only other options I have looked at are either a supercharger or a 383 stroker motor.

 

Someone I think mentioned some kind of a marine intake manifold when I performed a search earlier, but I can't remember where it was...darn old age!
