Check it with a fuel pressure gauge while on the dyno. As long as it
doesn't drop pressure more than 1-3 psi at WOT at the upper rpms, you'll be
fine.

I'm gonna leave it in......if I have a chance this weekend at the PGH
Chrysler Classic, I'll make a pass and see how it acts.......
I have a Dyno test with A/F readings scheduled for Aug 5, I'll know for sure
then on if it works right
for my application....
I'm betting it'll be fine, as I have never had issues with any Holley
product in the past....

I've heard of the Walbro pump being used in several repackaged pump setups.
Though the Holley piece seems to be the pump of choice among the go fast S/C
crowd on some of the other boards.
As someone suggested, the internals "may" be different. The probability is
the actual pump veins. The electrical portion of the pump can be the same
and it still have different outputs.
Try it, if it doesn't put out as expected, ship it back. Worst you are out
is the extra tiime for the swap.
My 408 R/T is using an Aeromotive 1000 HP external pump with a return
system, so I can't give you a good other choice.
