Ya Lee, that's a common mistake. No such thing as a mono-runner. The plenums pictured are referred to as Siamese’d. The plenums that have been joined internally only are referred to as a fully ported. Lot's of differance in flow and price...

I like to think of them as full siamesed or partial (figure 8) siamesed.... and then there is my B-port siamese

The Siamese port actually started with Gulstrand and then TPIS who both made a siamesed TPI runner....TPIS version was more like the one Locobob and I did.....

If it's mine, I'll call it what I want.

If it's yours, I'll call it what I want.

Default Re: If/When you go to siamesed Intakes?

I would think the separation between runners would become important with respect to cam timing of the two valves - do they open in unison (stock cam) or is there a difference in cam timing?

- Jeff the curious, who will wind up with exactly one chance to get it right and still meet class rules....

I believe the stockers have some offset timing and lift, my regrinds have different lift and cam duration for primaries and secondaries...there is also a dog leg to one port that acts as a swirl generator
