Depends on what you want, on the street you would never know the difference because you would not be doing 1/4 mile passes.
On the track if you have 6.5 at launch you could easily drop 2psi on top end which would not be enough. Depends on your combo and needs, just relating my experience, the hemi race pump works for me on the street and track with no issues.

... several people told me the same to stay away from the hemi race pump, after going through 3 diff carter 440 pumps I installed the hemi race pump and my issues were solved. I could have saved some $$ by buying the right pump in the first place. Honestly I think most would not know that they are fuel starved on top end because they don't work their cars hard enough to find out. If you do I think the choice is clear.

Just to be clear; the people telling me (and JD) are racing thier 440-6's in Pure Stock, so they definitely KNOW if they don't have enough flow. Most of these motors are pushing well over 400hp at the rear wheels.
As I said; my car isn't even running yet so I guess time will tell, but I was told by several people that the 8.9 PSI pump will cause me problems. Also, since the car is stock appearing, I don't want to run a regulator.
Don't get me wrong; I'm sure your setup works well for you, but I don't think that a healthy 440-6 NEEDS the 8.9PSI pump to run properly....even up to the 450-500 gross flywheel hp level.
cheers,

Oh, I just remembered another thing; my engine builder buddy was giving me a hand the other day and he took my fuel pump and checked it for play. He said sometimes the play is excessive and then you lose serious output from the pump.....just a thought  Dave

My 440 is a stroked 493 540 solid lift cam with Modern Cylinder Heads ported Stealth heads it needed the xtra volume. The other pumps fell off, and the pump puts out a max 8.5 that doesnt mean you get that psi at idle. My six pack is jetted pretty fat with a 50cc accelerator pump 3/8 line.It needed the xtra volume, the other pumps couldn't keep up and were a waste of money.

I did the same thing decades ago, playing with various pumps, Carter, Holley, and continue to do the same with customers and people building 6 pack motors,.....skip the rest, go straight for the race Carters,......on my 440/6 motors I run the Carter M4862 8.5 psi, and I've been running the Race Carter M6270 on my Challenger T/A 340/6 for about 20 years, after going thru countless Holleys and other Carters that can't keep up with demand in high RPM/ high GPM demands,.....but I allways swap out the rubber tipped needle seats to the Holley all steel needle seat assemblies,(costs about $50 for 3) as a high pressure pump can load a stock needle seat,causing it to stick in the "closed" position, and cause a starvation problem,(empty bowl) I've never run a regulator at all in 30 years of running basically nothing but 6 paks, never had one "blow fuel" past the seats, had Stock seats get stuck from overpressure or debri, but have allways gotten in the habit of tossing the stock seats everytime to avoid problems
