Technical New Oldsmobile 260 intake manifold

So my Olds 260 engine has been leaking antifreeze around the intake manifold coolant passages... I assumed the intake gasket needed changing.... only to find out that the intake manifold itself was badly corroded...

 

Might as well upgrade to a four barrel intake at the same time! ... The Edelbrock Olds SP2P is the only intake that will fit on a 260 besides the factory single plane two barrel intake

 

These 70's SP2P intakes featured smaller runners for improved low-mid range torque and fuel economy... in my opinion too small for an olds 350 or 403... but perfect for the 260! the triangular ports fit nicely in the 260 manifold gasket windows

 

Kind of a rare intake these days... you can find used ones for sale on ebay from time to time

 

Learn something ever day on the HAMB before this I never heard of an Olds 260.
