    my boy called me last night, finally got the new stroked 440 ready for break in! said he fired it up briefly the night before and it ran for a minute and stalled, no spark! replaced the coil with a new internal resistor and retried it next night ran 10 mins just getting to temp [cold here} and quit again ,no spark! He's running the box from the original 318 which had no issues [ I assume there all the same except rpm limit}
    I really have no answers for him, I've owned mopars but never had ignition problems! I told him to disconnect the old tach[grasping here, never really heard of one that lets the engine fire then quit}
    He will be trying again tonight if anybody has any ideas about the issue! He says the motor sounds great until it quits, now he's worried about the cam getting messed up with this intermittent run in! says the motor runs 70- 80psi oil on start up am worried it will blow the filter apart!

    Sounds like a classic pickup failure in the distrib especially if it get warm, dies then cools and starts. Oil will settle after break-in not a issue.

    the first attempt only ran for 30 secs. and quit ,no time to get warm! Guess I'm just anxious to get over there and hear this beast!
    does the ignition box require a resistor coil?

    Yes if it is mopar. If it used to be points you need the proper coil also. Check the ground on the box also.

      mounted a gm mogule on the distributor and now it runs good! getting pretty warm for just break in with no load! time to figure out if the aluminium rad and electric fan are big enough!
