from Galen's white books:

F - 1970 model year (G would designate 71 model year)
B - 0.10" undersize main & rod bearings
C - special crankshaft/pistons

The F would make sense, left over 440 blocks. Wonder what kind of special crank and pistons they would be? haven't been inside of the motor yet. if the bearings are under sized, guess that might mean a slightly beefer crank. guess i'll have to read up and find out.
Thanks for the infor. Eric

I also found a faint V just before the BC AUTO, could be half of the diamond shape they used
