HotRodDave, that spring info you gave is wrong. The 6.4 installed height is taller than the 5.7. A 6.4 spring CB is around 1.4. When installed at a 1.98 in an Eagle head you would be right on CB with a 6.4 cam.
Another thing, the 5.7s springs CB measurements are all over the place. From 1.30 to 1.37. However, the stock mopar springs have really stout pressures.
