I know that this is the wrong forum but hopefully Curtis will redirect......

I have a mix of Buick 215 and Buick 300 intake manifolds--- does anyone know a way to identify between the two?
It seems simple (perhaps) but I am having trouble getting it done.

The width. The narrower ones would be 215 and the wider ones would be 300.

Jim

Or post the part numbers here.

Also, the 300 intake covers/seals the lifter valley. The 215 does not.

Thanks guys---
Much appreciated...

Also, the 300 has a squared off bottom that seals the valley where the 215/Rover has a separate valley cover.

OK, it appears that there is no Buick 300 manifold amongst this lot.
Is there a good after market intake manifold that would suit a Carter 4bbl carb on a Buick 215 with 300 heads?

If you have hood clearance issues, use the OEM Buick 215 manifold. Otherwise, the Edelbrock 2198 is a smidge taller. If clearance is not a consideration,  the Huffaker single plane has ports that match the 300 heads better. Hard to come by & expensive.  There is also a Wilpower single plane, but has Buick/Rover sized ports.

One more intake is Offenhauser. Actually 2, The Dual Port which I had on a Jeep and 360 Equa Flow single plane. I think you can buy the single plane new but it is about $ 100 more than the Edelbrock. The dual port is more for lower RPM.

Actually, the Offy 4bbl and 2x2bbl. manifolds, are a smidge+ lower than the oem 4bbl. They are easy to port 64', 300 Buick size ports. They also work as a good base, to weld on a "Dyers Blowers", 6V71 mounting base,(even more work).  art.
