Cross utilization? Plenums
Was curious if the plenum and runners off a 87 chevy 305 are the same as on a 87 TPI 350 vette? Also, what about the manifold base? Appreciate any input! Thanx!

Manifold base is different too. Center two mounting bolt holes on either side are drilled at a different angle on the Camaro/Firebird manifold. Also the EGR systems are not compatible. The plenum extensions are different too. Corvettes are aluminum while the other type is plastic.
