When I was building my car I was willing to spend $2000 to port a max wedge intake. If it could be on par with an Indy 440-25. Couldn't find anybody. When the 440-25 was first released I backed to backed a factory crossram vs an Indy 440-25. Same day on the dyno, same carbs. 498 with box stock -1 heads, .650 roller, 12-1, 2 Eddy 750's. 658@5700 vs 712@6700. From 4000 up the Indy was better.
