Getting my 455 together and did a search for the best fuel pump for a 455, what is everyone using with good results (ethanol friendly) etc...
71 455 with 77 6x4 heads will most likely use the qaudrajet carb I have I believe its 750 cfm.
It looks like carter is building ethanol compatible units.
Thanks Bill

Stock ones from the parts store still seem to serve me fine, even with the dishwater gas. As long as the vehicle is used often enough to keep the pump wet inside, a stocker should last for years.

I have a mechanical stock type Carter(I think the M6907, 120 gallons per hour free flow) which Summit sells for $96.97.  They have several others in the $30 and up range.  Mine is about 10 years old, has over 10,000 miles of crumby California 10% alcohol gas gone through it with no problems.  My engine is a 1970 Four bolt main 455 with 74 4X 7H heads.  I don't know about E85, if that's what you might be considering, but the Holley's they have that they claim are alcohol race type are over $200.  Good luck Bill...

When I think of "the best fuel pump" I can only show you this:

I have one and know some others that have one.. it's just perfect.

Here you can see the difference, left = Edelbrock, right = RobbMC

Like Chris, I have a RobbMC fuel pump and couldn't be happier with it. It's a bit pricey, but the manufacturing quality and ease of working on it, to tear it down and clean it, etc.. beats all the rest in my book.

I have to add.. I chose the one with vapor return option, fuel pressure without regulator is about 7psi now, just fine for my Holley. Also the gph rating is much better than with most other fuel pumps. It will support up 550hp or you can get the even stronger one (+$100), but you'll need a fuel regulator with the 1100hp pump.

Edelbrock says their pump supports up to 600hp... but it couldn't support my engine and I don't have 600hp. The RobbMC is much much better!
