Hey, Mine is a 40 56S with a 263 from a 53 Special.Bought in Chicago from original owner's family.Otherwise the same as when it was first built except for the paint.

thanks,Ray

Okay,my 40 super that seized up.I poured oil in the cylinders and got it to run.Seems to have power but the smoke from St.Helen's has nothing on this.Going to do compression test once my son returns...
