[satellite400]

Hello mopar folks!


I have a very annoying problem with my 400 motor with 906 heads, purple cam, holley 750dp, yada yada...



I have replaced the following parts without success;
tested 3 different carburetors.
New spark plugs, ignition cables, ignition box, distributor. Fuel filter, fuel hoses, fuel pump.

I am stuck! please help me

Did you check the fuel pump pushrod length?

Sounds like it might be running out of fuel.
Or the yada yada perhaps.

Next time it dies check your fuel bowl or filter see if its out of fuel.

the pump pushrod is the right length.
