Time for an update on this...

He didn't drive it a lot but did get it out from time to time...

I don't think it gets driven enough to keep the fuel fresh and ethanol fuel got blamed for it running different from time to time...

He purchased 25 gallon of non ethanol fuel and put it in...

He never thought to make sure the octane was 93 and what was bought was 87 octane...

In September of 21 it broke a ring land on #8 piston between the top 2 compression rings...

Seven cylinders had 195# of cylinder pressure and #8 had 95#.

The engine was removed and 8 new Ross pistons are now installed...

I had it ran on the dyno to get everything set correctly and installed it back into the car over the w/e...

I also installed a new convertor built just for this combo...

Drove it about 5 miles yesterday and everything seems okay...
