Not sure but it might be a slant 6, I'll check for you next time I see t and get more pics of it.
There is another show today a few miles from my house so I'll take some more pics there too...looks like some rain on the radar but the show is free and being close, can always run home if the weather gets soggy....it's at a pizza joint and they have good good, getting close to lunch time :glasses7:
