429 is pissing me off!! I have no idea anymore as to the problem! Please Help!!

Fuel lines from the tank all the way forward are 1/2 aluminum fuel line and the fuel pump and tank setup all came from Summit Racing and was ordered by the motorhead that built the motor. The tank is half full but makes no difference because I can burn out in second gear just fine. Plus when my tires are hooked I am pulling more G's than I am when I haven't gained traction. I can't say that I sounds like fuel because it's only in one gear under heavy load and RPM's flying up to the roof.

Here is my setup:
MSD 6AL # 6420 Multiple Spark Ignition
MSD Pro Billet Distributor PN 8477
2 grey springs 1 large gauge with 4 wraps and 1 small gauge with 5 wraps
MSD Blaster SS PN 8207
I have a racing fuel cell with racing pump and 1/2 fuel line from the pump to the carb..

commercialcobb A first name would be nice to call you, anyway What kind of fuel pump are you running electric or off the motor? Aluminum fuel lines are having not the best to run for a fuel system Methonal in the gas is on the rise. Do you have ANY rubber to maker connections? Octane booster, E-85 gas will eat the rubber and degrade it into little balls of goo. You need to full the fuel cell and check to see if there is a one way valve in the fuel cell. As others have said some gases break down the foam in the fuel cell.
Down the road I would also tell you to replace that Aluminum fuel line with either steel, plastic, or SSteel line. Aluminum is not safe for a street car. Some states will not allow you to pass inspection for the state with this kind of line. NJ is one of them. For now, you might want to have rubber clamps every 12" to stop any vibration of the line. I have seen pro street cars burn to the ground from running Aluminum lines. They where doing this because of the color blue and red coatings.

By racing fuel cell and pump I mean they were performance parts ordered from Summit Racing. This car only has 120 miles on it. I can't imagine the fuel cell going bad.

Where are my power and ground wires from the ignition going?
I just checked and the power is conected to the starter where the 8 gauge wire from the positive terminal is mounted. But that wire also goes through a shut off key mounted on the back panel of the cockpit.
Should I re-wire directly to the battery? Will that keep the box charged and burn it up?

And the ground is grounded directly to the block. Same thing, should I run it to the battery as well??

The fuel pump runs through a relay set through the engine oil pressure so in the event of oil pressure loss or in a crash the fuel pump will shut down.. I am a Pilot and very perticular about safety..

Is there a better set of advance springs for the dist. that would be better for my setup or maybe the advance stop bushing needs to be replaced with a different size?

My problem only exist at full throttle in first gear at 4000 rpm with tires spinning. Tires not spinning and it fly's right on through 4000 with no problem..

Would changing the max rpm ship in the MSD do any good?? We never plan to break 5000+ rpms anyways. It just sounds way to wound up for are liking.

I am not asking you guys to re-build my engine, just looking for another option since all mine have failed.
