We have been fighting this problem every race so far.

The car falls on it's face in the corners, but will run very strong mid straight away...strong enough to throw your head back.

Claimer 350 w/ flat tops & Vortec heads. Holley 7448 2 barrell with 73 jets, stock fuel pump. Timing set at 36.

So far we have tired 3 separate carbs, 2 stock fuel pumps, 2 distributors, new wires & plugs.

This last weekend it did run good for about 5 laps before the cutting out surfaced again.

This week we are changing coils, caps, & electronic module.

Also..It was mentioned to me that the headers were glowing this week when I left the track.

Do you run a vent in the float bowl?

Check the pickup location in the fuel cell. Should be in the right rear. Saw a car with the same type problem and found they put the fuel cell in backwards and the pickup was in the left front and would go dry and the car would stumble.

pull your air cleaner and bring the rpms up slowly and look down the carb to see if pullover is occuring and flooding it or causing a severe rich condition.

try and see if it's related to something that is specifically happening in the corner or if it's related to the rpm you are at in the corner.

when you are in the corner and the problem starts, look at your tach and see what is your rpm. note that rpm. for example, let's say it happens at 4500 rpm.

now the next time you go into the corner, go about 1000 rpms slower, 3500 rpm. when you exit the corner and start down the straight and you get back to 4500 rpm does the problem occur?

if it does occur in the straight at 4500 rpm, then it's related to rpm and nothing specifically happening in the corner. if it does not occur in the straight at 4500, then it must be related to something specific to cornering.

if your decrease your rpms down to 3500 in the corner and problem is still there, that too points to something that's happening specific to cornering.

Thanks for the replies and definitely some things we will double check.

BTW.. The plugs looked great.

Are you using a slosh valve ? If not this can cause a similar effect.
