I HAVE A 1973 WINNEBAGO WITH A BIG BLOCK MOPAR MOTOR. THE GUY I BOUGHT IT FROM CLAIMS IT IS A 440 BUT A LOT OF PEOPLE TELL ME THEY ONLY PUT 413's IN THE BAGO's. IS THERE A SIMPLE WAY TO TELL THE DIFFERENCE BETWEEN THE TWO. I'M HEARING TO MANY DIFFERENT VERSIONS OF BULLSHIT ON THIS MOTOR. I'M NOT A MOPAR MAN AND WOULD LIKE TO SELL THE MOTOR BUT WANT TO KNOW WHAT I'M SELLING.
THANKS
