olds firing order

got a 48 olds i'm working on and i can't find the firing order.it's an L6 engine.did a search no help.anyone know off the top of their head? thanks

 

it should be on the intake manifold.

 

don't see it,i thought so too

 

IIRC, all straight 6s use that one. Waaaay back, I had to learn firing orders for a class. I did well, but the other students....
By the third class, I had the jag V12 and others memorized....

 

I quiz my grandson 53olds "what is the firing order for a small block chevy? what is the firing order for a inline six? he now gets it right almost everytime!

 

thanks for the help,when all you work on late model crap and diesels you tend to lose your memory,or your mind, if you know what i mean!
