425 shipped OBO. Upper has been ported by Scott Yellin, knife edge lip port matched with the lower manifold. I made 315hp+ on E85 with this. I recently switched to the GTR manifold.

 

And here goes more parts I can't afford! This would definitely help me break 300 wheel


Any idea on power vs stock mani?

 

Stock mani, Stillen CAI, ART pipe and Motordyne I made 289 tuned.

Ported mani, 3" CAI, PPE headers, Motordyne, GTR injector, E85. I made 315whp semi tuned. Could have easily made 320 if I had a tuner on the spot.
