I agree onthe floats. Check and make sure they are set correctly. you might be overfilling the bowls and the sputter is actually from too much fuel.

Chech the bulkhead connection just where the line goes into the cell. A little vacuum leak there will drive you CRAZY!!!!!

With a side hung float it will shut off the fuel in the middle of the corner and not let it open until the car enters the straight then it will start letting fuel in,i think you can adapt these to center hung and then the problem will be fixed.Some guys run them but from what i've seen they have to keep the fuel level very high in the bowl to try and delay the fuel starvation but it's only a crutch.

rusty i believe this will solve the proplem with the fuel line i think if u measure th original line you will find it is only 5/16 on size not a true 3/8 also i would eliminate any small in line filters between the pump and the engine those little small little glass filter u buy at the parts store have more restriction than the larger in line filters eams is a fast track and with a carter pump it doesnt take but a second to drain the carb also good luck on the big money sat nite had thought we may come run for but things came up

Since your sputter is coming off the corner, and not at the end of the straight where the engine is at max rpm, your problem probably isn't the fuel line. A small line would show up when the engine was at max rpm and not enough fuel could flow to feed it.
On a holley, get a high flow needle & seat, get an angle cut float, and use jet extentions. The other thing you HAVE to do, is get rid of all the rubber hose. It's hot under the hood. Rubber gets soft when it gets hot. Soft rubber collapses, shutting off your fuel supply. Get some good #6 Racing fuel line to get from the pump to the carb. Run #10 from the cell to the pump, and get a good in-line log filter.
