Holley 350 LPH Fuel Pump Too much for Gen 3 392?

[PistolGrip6]

I have a Holley 350 LPH EFI In Tank Fuel pump installed in my Coronet that is in the midst of a Gen 3 392 Hemi swap. Stock 392 (485HP).

Was just wondering if anyone has some technical knowledge that can let me know if it’s too much pump for my application.

I can’t return it. I bought it thinking that it’s better to go bigger. My recent internet searches have me worried that is not the case.

It should work fine. It is a more expensive pump with the capability of supplying enough fuel up to 750 HP. Seeing you own it and can not return it I would run it.

Appreciate the response. I’ll give it a go and see how it functions with my set up.

350 LITERS ? That's way less than a 40 year old holley blue, 110 GALLONS per hour.
You're fine.

350 gph might be too much.... but thats FOUR times the pump you've got.

Don't you have to run a return line? Adjustable regulator should take care of things.

Pump is supposed to be a returnless system. Also has a built in pressure regulator (58PSI). I think for now I’ll try it out as it is, and if it’s causing me problems I will set up an adjustable regulator and a return line. Thanks for the input.

I guess time will tell, I’ll set the system up as it is now and adjust if needed. Thanks for the input.
