Hi guys,just had a 493 stroker built which made 576 Hp and 615 ftlb of torque on the dyno. :icon_smile_big:
Firefighter Ron pointed me in the right direction, so thanks Ron for your time and suggestions on the build which I do intend to but up on this site.
I could do with some help again on which fuel pump to use with this combination. I had intended to use a mechanical pump like the Carter strip super but my engine builder suggested I needed a higher GPH and recommended the Holley black electrical pump. I'm not keen on electric pumps and would prefer to stay with a mechanical unit.
Is this possible on a build like this or would it run lean at the top? The Carter pumps free flow is 120 GHP.
If I do go with the Holley I've read that mounting it on the rear shock cross member is a good position but it would sit above the tank which as you know is not recommended by Holley. Also I have a Dana 60 which does tend to get in the way.
Any help would be greatly received.
I have had several Holley electric pumps on various cars. All have left me on the side of the road. All removed and replaced with reliable mechanical pumps. If you do use an electric pump opt for a higher end pump. They are not cheap, but more reliable.
after all the fuel pump pushrod issues , I went with a Tanks inc setup in tank efi pump with a return regulator.
It may, or may not work with the mechanical pump. Just try it. Put a gauge on it so you can see the pressure while driving.
What about a CV products billet mechanical fuel pump? These are NASCAR pumps and support up to 800hp (depending on spring used) and the best part is they fit Mopar 440 blocks! Used ones are available on ebay (make sure to get a Doge version - the Chevy, Ford versions do not fit).

I'd advise the same. You can try the mechanical route like BSB67 said, but if it comes up short I would just go in-tank. It is getting easier and more cost effective. Similarly, another perk is that if you just built the engine you can get a new tank and run new lines.
Should be a really nice mill for street/strip action!
