Single plane or dual plane intakes
 

I have 468s in a 28 Pantera with single plane team G intakes 850 carbs. Crane roller cams lift at valve is .578 in.&.595 ex. the duration is 232 in. & 242 ex. and Stainless Marine dry exhaust. Would I get better performance with dual plane intakes???

I would leave it alone.

Dual plane intake would give more torque down in the 3 grand range, but would start to lose out above 4 grand,,,with the cams/setup your running,,,personally I'd leave it alone..changing intakes with the setup you've got you'd never be able to tell/feel any difference.not enough hp differences to be able to feel anything..save the money and buy gas..
Just my personal opinion

slick is on the money think about what you want!!!!

Hot Rod magazine does a lot of dyno testing and a recent article stated very plainly that an Edelbrock RPM Air-Gap was the best intake they've ever tested for engines smaller than 500ci turning less than 6,500rpm. It gave up only a few hp on the top end vs the single plane but retained the low end like we all know duel planes do.

So, single vs dual? Edelbrock RPM Air-Gap high rise dual is a damn good bet for most boats and cars.

What would that intake do for your engine? Probably fatten up your low end and mid-range a little but like others said above not likely to be worth the money if that's all you are changing.
