298 stroker build...which water pump and which limiters?

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.

The OEM pump should be fine.
As for phaser limiters, the Comp versions are a single plate and aren't likely to fall out of position or fail as easily as the Livernois units, so I think the choice is a no-brainer.

Did some more searching...found multiple threads with Livernois carnage. I'll stick with Comp unless someone has a good reason to convince me to go with Livernois that is safer than Comp...

Here was Tiger Honaker's failure:

DOB also had this Livernois failure:

Then on the other hand...Retr8flyer had a failure with Comp limiters:

I don't run limiters, car runs like a cat's ass!

Here is a good build thread from the annals of S197 history:

no such thing as a good limiter, lock them out or leave them alone. comp limiters made my car do some weird shit on the dyno so I just locked them out and problem solved

I can’t leave them as I could have piston-to-valve contact.

I want to keep VCT intact somewhat; it does some good things down low.

I’ll do the Comps.

Definitely don't use Livernois they are crap and do fail, as others have said. Mine is personal experience.

Been running the comp limiters with revised phasers for about 8 years now.

Tell me about these “revised phasers” please...

all new phasers comes with a different spring and spring profile which is basically an added bolt adding pressure. came standard I believe on mid 07 -up cars

Comp limiters for over a year and 100lbs of nitrous, zero issues

This. My 07 had them from factory. Were revised late 06 for mid 07 model year iirc. Change afaik was a better spring/pin design. Just one Ford part number for the new design 3R2Z-6A257-DA and can be used on either side. They have L and R timing marks 180 out which is a quick way to tell visually. Vice old versions had 2 part numbers one for each side with either a L or R and then a notch on the other side.

How many miles and under what conditions do the Livernois fail? Mine have about 15k on them

GREAT information; thank you!

I have a couple sets of phasers in the garage; I’ll have to see if I have any revised units.

I bought the Edelbrock water pump, for what it’s worth.
