engine codes for marine motors

**John** · #1 03-10-2005, 04:05 AM

...saw a 427 motor ( 1968 ) with a code of "BJ" on the front pad....4bolt main motor...
Is there anywhere that list the codes for "Marine Motors"

"270's" are typically Corvette 427 Blocks. I had one that was an IF or something like that, with an "I_" , but it didnt show up on any Vette lists...Good Luck!

Maybe that "BJ" coded engine belonged to Hugh Hefner.
