Well guys i have officially started my high hp 6.9 build, 17.5 to 1 comp, aftermarket cam, studs everwhere, peened rods, oringed block, 60% over injectors, s466 charger. Now i am trying to figure out a pump, the thought crossed my mind of doing a p pump but it will be a huge pain. My question is what is the absolute biggest plunger that will fit in a ds4 rotor? I have done the math ( dont kill me if im wrong) and it looks like a .450 plunger will get me where i need to be fuel wise, is this even close to being possible or am i nuts ( very possible). Also will the ds4 guts go in a db2 housing or does it need to be a db4. Please help before i lose my mind thinking about it.
