Inliners International Forums General Discussion Engines Questions on Stock GMC 302

I found a 302 GMC engine in a 1950’s (?) flatbed dual wheel truck. I confirmed that it is a 302 by the number stamped on the raised casting by the distributor. It appears bone stock and complete except for the missing air cleaner. The engine is for my 1937 Chevy sedan project. A couple of questions:

The 302 has a dual outlet exhaust manifold. One outlet is directly under the carb and the other exits farther forward. So some GMC engines had dual exhaust?

The engine has a 2-barrel carb. Is this stock?

I did not see an oil filter. Maybe it was removed? Where should the filter be, on the intake manifold?

I’m familiar with the chevy 235 engines but not the GMCs. Thanks for any help.
