Default Converter offset to full seat

Anyone know how much a converter should be offset from the transmission mounting flange to ensure its fully seated? I'm coming up with .644-.650.

I never measured mine but I know that to mount it to the flex plate I pulled it out about 1/8" when the motor and trans were bolted together.

Sorry I couldn't be more help.

Don't know the exact measurement, but measure from the back of the block (where trans mates) to the face of the flexplate (where converter bolts up). That should be a little more than your measurement that you came up with. The measurement that you came up with will vary a bit depending on the converter. Some are a little thicker than others.

Another good way to check if the converter is seating all the way in the trans, is to take a dab of grease and put in one of the two notches on the converter snout (assuming this is a pg/350/400 converter), and see if the grease is compressing when you install it into the trans. Those two notches is where it engages the pump.

.

I was always taught 3/16" gap between plate & converter.
That's why we weld on spacers when adding mid plate.
If you still have too big of a gap, I use grade 8 washers.
