Editing Talk:Cadillac engine knowledge

More than 472's and 500's
anyone with an interest in old caddy engines?
these engines are very simple and and have potential too.
parts are plentiful, and accessories for performance and dress up 
can be found. With the new adaptors, tranny choices make installation easy. I have found these engines to be very quiet and smooth, in stock form. They look especially cool with the old signature valve covers. So anyone with knowledge about interchange of parts or speed secrets, please join in and share your expertise.

How do you identify cadilac 425-472-500 engines by year and cubic inch without the car?
