What is it, just curious.

 

Creitz Dual Quad Aluminum Intake Manifold SBC Chevy with oil fill in the front , what’s the question?

 

Thanks Tuned. Never seen anything like those intake ports.

 

People used to do that to single-plane intakes alot; just cut that septum out between the ports. I'm not sure how beneficial it was. Seems like even though the flow might be better, the loss of port velocity would offset any gains.

On some heads, people would go crazy with the grinder and "knife edge" the common wall of the ports, the same kind of way. Again, not sure if it really helped or not, or maybe in what situations it would work.

Earlier SBCs all had the oil fill in the front like that, from the factory, up through about 68 or so.

 

Would be pretty cool to see how it performs, like on an episode of engine masters.
