Motor has less than 3,000 miles on it and is barely broken in. Ran great, pulled as hard as when I had my supercharger on the L31 with 7 psi.

Lot of hours and $ into that intake. I was very satisfied with how it performed compared to the stock intake; wish I could compare it directly to the marine setup but I was into building my intake before James B. et.al came out with the marine setup. Either way I couldn't bring myself to put a heavy ass cast iron piece on top of my engine, but that's just my bias. Unfortunately funds became tight after I went another direction with the truck build and I'm having to unload a few things that I would have rather kept for my Tahoe (intake, ht383, etc. 
)
