Hey everyone!

i bought a 1977 Dodge RV last year... I’m finally getting time to work on it so need to order some parts. However, I’m not sure what engine I have.

The passenger side exhaust manifold is stamped 422637-2 , so based on a google search it’s a 318 or 360? Looks like it could fit on either, but I’m not familiar with Mopar engines... I need to order spark plugs and an exhaust manifold gasket, any help is appreciated! The RV is five hours away from where I live so don’t have access to it, just trying to get some parts ordered before I head over there.

thank you!

 

Look on the side of the engine block at the casting numbers behind the engine mounts... Should see it in the casting...

 

Unfortunately I won’t be able to get to it until the first week of September, was hoping to get parts ordered before I get there because I don’t have much time. I might have to do that though, thank you

 

i wonder if someone can go look at it for ya?
