Nah bro, these are twin 380's. (400's according to Aeromotive but we know better.) they draw about as much current as your typical 300 pumps. Been running them for awhile before this setup and so far everything looks cherry.

They're both fed with their own separate 12 ga harness though. but yes, the pigtails are 14ga.

You guys think it'd really be worth it to upgrade to dual 12ga pigtails?

I mean I see that Scooter K has a Lonnie's setup which utilizes twin 340's and stock pigtails so.....?

What waste gate you going to go with?

It's the one that comes with the KB kit. I believe a 50mm JGS or something like that.

Standard is the 40mm jgs.

Go with the 50 or 60mm gate. Vband alone is worth it. And get the race version, easier to change springs.

Yup just found out it's a 50mm JGS. V-Band, not sure about the race version or not. I assume that it would be though.

So unfortunately after getting everything all clamped down with my dual pump fuel system I found that I have a checkball in one of my pumps that is leaking. no bueno.

Also if there are any mods in here can we get a title change to "Gray Ghost turbo 427 LSX build"? I sure would appreciate it!
