THANKS FORTHE REPLY. THIS IS WHAT I HAVE SEEN. ON
WWW.MYMOPAR.COM UNDER ENGINE CASTING NUMBERS IT SHOWS 71-72 WITH 400 2BBL ECN(3614230). I ALSO HAVE A RELATIVE THAT HAS GOOD FRIEND THAT WORKS AT BARRETT JACKSON, AND HE ASK HIM ABOUT THIS AND HIS REPLY WAS : THERE WAS 8 CARS IN 71 THAT HAD 400 ENGINES AND HE HAS ONE. I DID FIND A SITE OTHER THAN MY MOPAR THAT SHOWED 71 MODEL WITH 2BBL AND A 4BBL, BUT I DID NOT SAVE THIS SITE. SO, WHEN I FIND IT I WILL LET YOU KNOW WHAT IT IS. THANKS-
