Just mentioning some basics hadn't seen mentioned.
electric style gauge readings can be screwy sometimes,have seen sealer on threads of sensor cause bad ground for sending unit and read incorrect or not at all.

Hi Mike,
The gaskets are on correctly. No insult taken.
The water pump is a Pro-Form Electric. The owner is going to try swapping a Meziere pump off his other car, as well as removing a medium size restricer from the T-State housing and test.
As for the sensor, we are referring to a 3 wire sensor for the Holley EFI data log. We have tried another sensor with same result to rule that out.
Also have found out that the car had a puke tank for the Radiator and he changed that out to a recovery tank. Once I hear results of testing after these changes I will update post.

Thanks- T Gross

Update*
Customer tested last night. No problems. Monitored during multiple runs.
Although 3 things were changed, I believe the addition of the recovery tank was the helper here.
It appears that the Siamese cylinders of the Dart block is not as forgiving when it comes to moving air pockets that were introduced after cool off.
