I though .002 might be too tight, I checked the service manual & it had .002-.010 for range.
It is a ATI convertor, sent it back to them. Asked about it ballooning, no concerns found. It was freshened up at that time also.
It is footbraked to 3K to leave.
Another racer was having the same problem with a 340 Stocker.
He recommended me to a guy at Pro Trans.
They have a piece called the "destructor" that goes into the convertor charge hole.
I haven't disassembled the engine from this last failure to inspect the bearing yet. Just cut the oil filter open, found bearing material & the crank has excess movement.
I checked the crank during the last race, it didn't kill it until the last two passes. Also lost a tenth at the same time.
