As title states, which water pump should I buy? I was just going to go OEM (M otorcraft PW496 ($79) but I see Edelbrock has their Victor series ($189) which has a bigger bearing and CNC-machined internal housing - and they claim it flows more. American Muscle has an OPR branded one for $50 (possibly a reman OEM?) I don't care about the cost, I just want a good one. Leaning toward the Edelbrock. I ask simply because sometimes OEM is best (coil-on-plugs come to mind). Topic 2: I also have both Livernois and Comp phaser limiters. Which should I use? I've read bad things about both. Leaning toward Livernois.
