Anyone out there with a naturally aspirated motor need to upgrade the stock fuel pump?

Assuming I can get my block repaired, I'm considering a 535ci bored and stroked n/a engine with flowed heads. I'm wondering if the stock fuel pump would be up to the task.

What kind of issues have people run into when upgrading the fuel pump on a Gen III?

I figure that many of the twin turbo and supercharger engines must have upgraded fuel delivery. What are you turbo and supercharger guys using? Weldon? Bosch? Walbro? In-tank? Exterior?

I personally like the Walbro 255 LPH In Tank Pumps. These are the same pumps as the car has OEM, and have OEM reliability. Good for ~600 RWHP each. You should not exceed one of these without SERIOUS engine work or forced induction.

From What I have seen, these are some of the issue to be aware of when it comes to pumps:

-Aeromotive pumps are not reliable
-Barry Grant Pumps are not reliable
-Weldon Pumps are reliable, but noisy
