Single plain intakes for small engine with FI

rumblefish360 said

I haven’t been there or done that... with that said, have you tried a single plane intake manifold? And which one? On the smaller displacement engines, IF the normally found/known single plane intakes were not friendly, perhaps a smaller runner intake from days gone past would help.

I'm thinking along the lines of the likes of an old Torquer or one specked for a 273/318. I’m not sure anymore what’s out there in that nature. But I have noticed the older single planes have reduced plenum volume by compare to what is being made today. This could help.

Thanks for the reply, That's kind of my thinking. Smaller intake designed for a 273 / 318 vs most of the intakes are all designed for the larger ports and the difference in the head to intake port causes turbulence. The older single planes were tough on the street in a bad way. Back in the 80's I tried many out but with WAY less knowledge I have now in my 50's about how to make power.
there is no stumble with FI engines today and if their is... there is a part broken. Most factory cars run flawless minus a few small individual issues. Now trying to find an intake to just "try it out" is what I want to do.
I'm just curious if a single plane would correct my tip in hesitation on the FI Tech set up.
It sometimes feels like its laboring - ive watched the numbers and boy do they cover issues with more fuel. A/F ratio goes to 7.0to 1 on accel then will auto correct to 12.0, 12.3 to 1 after a moment of too rich. Same hill, same mashed foot- its just interesting to watch the numbers. I imagine with a "universal fuel injection system" They have to have some protocol to cover stumbles and part throttle decel under ever vacuum drop from any engine CI size. Way above my pay grade. BUT none of the systems on the market I've looked into recommend a single plane over a dual.
