I would do dual pumps personally and the rest sounds fine for your power goals.

This. The 340 may work fine, but dual in-tanks seem to be the preferred method. Both Blackbird and I use dual walbro's, one on a hotwire kit running constantly, the other on a "homemade hotwire" activated by a hobbs switch at x psi of boost. I have a 5 psi switch.

what brand injectors are susgested?

I'm using Siemens Deka Evo injectors, I got them from username JeremyF on LS1Tech. They were a sweet deal, and are flow-tested. His company sells all types and sizes of injectors. Get ahold of him and tell him what you're looking for. Assuming I'm completely on board with what you're doing, you want 60# injectors, LT1 style harness hookup, high impedance.

+1. This is what I am running as well. Dual in tank 255 lph pumps have been proven to support 1,000 RWHP so it should be more than fine. Be very cautios of your fuel pump selection though. There is a sticky in the fuel section I started on this. Read more in there for specifics but there are quite a few Chinese knockoff Walbros out there that are known to be faulty.

I reccomend and use Motoron 60# injectors. It is what was reccomended to me by my tuner, and after I did more research I found that they are a very superior injector.

^ Good call on the knock offs. I purchsed my pumps from speed inc, they are genuine.

Just because they come from a reputible vender does not mean for sure they are not Chinese knockoffs. There are specific ones like"racetronix" that are known to be safe. Others it does not matter where you get them, they could be faulty.

Siemens Deka high impedance and flow matched here. I have 80s but I wanted a bit more room for my power goals.

I read all the info on how to determine whether a pump is a knock-off or not. Mine aren't. I was just stating where I purchased mine, and that the pumps I received were found to be genuine.

Gotcha. I was just making sure you knew that it really doesn't matter where you get them, because that won't make you safe just because you buy them a certain place. Sounds like you read the thread, but anyone else lurking around on here I just also wanted to let know that location of where you get the pumps doesn't matter, as the knockoffs have been found almost everywhere, including from Speed Inc.

thank you for the info! and i have read the wright up on the walbros. that why i was looking at other pumps.

also, are you guys using stock radiators? never thought about that till my boss brought it up. will the LS7 lifters be good enough or should i look in to a different set? Oil pan wise im thinking of the MOROSO 5.5qt pan? will that be good enough for a HV pump?
