LS and fuel tanks

[vht]

What are you guys using for a gas tank with the ls motors? I've got a 6.0, planning on 550 hp, maybe not right off but later, if I go with inj I would like to have a system that works. I have a 70 chevelle tank, but if I go with a internal pump, don't think that's going to be deep enough. I don't want a tank that sticks down where it stands out like a sore thumb. Everybody says not to use a external pump, but with a return line and it not dead headed, I don't see why it would run hot. If you stick a pump in the tank, it's going to have to have baffling. 1st off will be a head change and a cam, lifters, may pull it out the following winter and make some changes so I'd like to do this once. What do you all think? Can't afford 1 of those $1000 tanks, this is a budget deal.
