Will it be enough fuel pump for a 416 Ls3? They say up to 600 hp but I'm thinking I might be around 650. If not whats the easiest & most reliable way to install the aeromotive 340? Its a 2000 SS

A single 255 SAFELY will support mid 400's at the tire. Maybe a snidge more on the slightly less safe side. I would never say 600 at the tire would be achievable safely with a single 255 lph pump.

What size injectors?
There are people who have pushed a 255 close to 600 to the wheels, but its typically in a very well balanced setup. Larger injectors allow you to run less fuel pressure which stresses the pump less and gives you a higher volume.

One 255lph pump is not going to support that. This is what I would reccomend. It is very well priced and an awesome unit from a reputable vender here.

The dual 255lph pump setup is $210. From everything I have heard, read, researched and seen, one 255lph pump is only good to 400-450 ish RWHP. More than that and you are really stretching the pumps capacity. You do NOT want to skimp on your fuel system. It's not like deciding to go kind of cheap and going with Eagle rods instead of Oliver rods. Both of those will work, one is just more high dollar than the other. A fuel setup comes down to science. There's what is required for the amount of power you are running and then what you need. Do less than that and you starve your engine of fuel, costing you WAY more than a good fuel system.
If NOTHING else, before you decide, call Lonnie from Lonnie's performance or at least talk to a fuel vendor like Racetronix and ask them before you choose, if you don't want to take my advice.

In my mind, the proper voltage sent to the pump should operate it normally and it is the limitation on the pump itself, not the wiring or voltage to the pump.

Do you have a link or reference for this? Never heard of a wiring kit making a pump able to physically output more. Not saying it's not true, just looking for some more info on this.

I looked at Lonnie's Performance website and I didn't see any "Hotwire" kit. I saw lot of fuel pumps with wiring assemblies but the wiring seems like a standard wiring setup and again I don't see how that would improve the output of the fuel pump. The single fuel pumps are still using the 255lph fuel pump which again I'm not seeing anywhere where it says with a "Hotwire" setup it jumps the capacity up for the pump.

Holy crap that's kind of a rip off if that's all it is. The dual in tank pump setup for $210 is good but the rest is really not anywhere close to that amount to do.
I currently have a dual in tank setup, with it plumbed to kick the second pump in off a HOBBS switch, direct lines from the battery to the pumps already. Besides the cost of the pumps, I have maybe $40 in the HOBBS switch, the wire, and the plumbing. It just does not cost that much (or should not). I bought thick gauged wire and good plumbing parts too, (it's not like I skimped).
I've got pics of my setup if anyone wants them posted, as you can have the exact same setup for WAY cheaper than $650.
FWIW, I still don't see running direct voltage to the pump gives it a stronger ability. Even with direct voltage as I am doing with 2 pumps, I certainly wouldn't consider rolling around with one pump and 600 RWHP, but again, if Lonnie says it's good, then I would trust his word.
