I plan on running a mild/stock engine with, tune, headers, and ls6 intake (maybe a cam soon) in my chevelle and drive it for a while but eventually I want to pull the engine and use all forged internals for a modest /reliable twin turbo build. My question is what is a good start as far as fuel line diameter? Is 1/2 line too much for a stockish motor?. I will be starting with a stainless tank from ricks with the factory style fuel pump (for now) but other than that I dont know where to go..I heard the "corvette" style fuel filter/regulator is common but does that mean I will have to use aftermarket fuel rails with my motor? is this a reliable setup? Is there any setups that I should stay away from? THANKS IN ADVANCE!!

Let's see, what little I have heard/read/might actually know:
The Corvette filter/regulator assembly mount back near the tank, so only one line runs up to the engine. Therefore you don't need anything custom for fuel rails. You could feed each individually, or just plug the outlet where the regulator would normally mount.
1/2" is not too big, though you might not need that much. For a "modest" turbo engine 1/2" is overkill, but if you've got the room to run it and want to be prepared, just in case, then go for it.
I'm not 100% on the whole fuel pump thing, but I was told by the guys that did my tank not to use the LS1 fuel pump. They used a Ford application pump, as they were more reliable. Both were rated for 65 psi and IIRC made by Walbro, so I don't know what the differences are.
