Also, I was thinking back about the "row vs. bank;" All radial engines with multiple "rows" or "banks" of cylinders are offset for better cooling and for better rotational balance. The P&W R-2800 and W R-2600 etc have offset rows as well.hate to be nit picking. but on the 4360 it was not refered to as 4 rows with 7 cly,s. it was 4 rows and 7 banks as the cly,s were not in line but off set .
I wish everyone a XC-99 load worth of Christmas Blessings..
