Was thinking about buying an electric fuel pump.
Although I don't know if it would be worth it, my 302 is fairly stock, only upgrades are dual exhaust, Holley carb, edelbrock performer rpm intake, shift kit/automatic manual valve bodies, and a cam that is VERY close to stock.
Looking towards the not so distant future though, I hope to have new aluminum heads, ported and polished, and have a nice cam to accommodate the rest of the engine.
So should I go ahead and buy one, or should I wait, also, what is a good maximum psi, and flow rate?

 

I don't see any need for an electric fuel pump. There's nothing wrong with a good stock replacement mechanical unit unless you're flowing a ridiculous amount of fuel, and even then you can get aftermarket mechanical pumps that will cope with that. Electric pumps are great for high-pressure EFI systems, but they're a pain to install (you need to wire some sort of cutoff in case of a crash) and benefit is negligible for a carbureted setup.

 

My car had an electric fuel pump on it when I bought it. I'm switching back to a mechanical one since the electric one was leaking. Also I'm having an electrical problem with a battery drain. I am switching back to a Holley fuel pump. I would think if you're still wanting to go electrical you should wait till you get your engine set up done, then again I've pointed out I'm not mechanically inclined.

 

If you're staying carburated stay mechanical it's MUCH simpler. I have an electric and they're noisy as all getup unless you modify it to go into the tank (which'd be a neat trick). And you need to rig up a relay and suttoff etc. I'm planning an EFI swap so I'm okay with the downsides, but if you're not I wouldn't bother with it. Just my $.02
