Hello
Today I picked up some manifolds I found on CL. The ad claimed they were off a 89 Burb with a 350. But they are a different design then my 87 manifolds and have no A.i.r injection port or O2 sensor fitting. So after some searching I believe they're off a C/K 88-95 engine. So my questions, Will they work on my 87? To me it looks like I'll need a new y-pipe. And why don't they have the emission stuff?
Thanks
