thanks guys...

so how was the 377 configured?? I assume it was a 4" bore?? And a one-off crank was used?? Im sure I could figure it out by using math, but I guess it is easier just to ask here..What would be the stroke?? assuming the bore 4"...I think Ive seen 377 ci aftermarket crank and piston kits for sale, havent I???

thanks again...
