Its been interesting to see the development of the cross ram runners through the years. Regardless of carb placement it allows longer runners with a lower hood profile. Though the design is close to 25 years old now the Indy 440-25 is the most modern of the wedge cross ram manifolds. There have been had several ideas to make them better. The first is pictured here. To be honest I dont think anybody is running this mod anymore. The second mod has been to run a vertical plate front to rear placed between the intake runners at the base of the runner entrances. Ive seen a third mod where the angled runner entrance center dividers were milled back to vertical. Not sure any are really any better. Though some have gone quicker with the mods, some not. Mine is still box stock.
