Two different styles of long tube headers. Haven't gotten to researching them or the nos melling high performance cam. Cam measure out at .428 with 1.5 so just ails street cam. Haven't looked at the complete engine yet but was told it's a 74 . Good running engine he was going to drop in his car before he got a nice 273 for his 64 valiant convertible that he has had since 73. Real cool guy.
