Thanks for the link, there is some good info in that thread that I haven't seen in other threads. After reading that and other threads I may actually try going with a fuel cell first. The fuel pickup is so bad in the already modified factory tank that i'm not sure a swirl pot would help me when there is 2 or 3 gallons left in the tank. Right now there are problems with fuel pickup with 5 or 6 gallons in the tank.
A conversation with an expert might be what I need at this point. And after I'm done conversing with Sam Adams I'll consult a racing expert.
