just for conversation: single plane on mild street engine
I definitely don't have the money yet.. you know life keeps getting in the way.
I have a mild 385 stroker, older 190 afr heads, mild comp 270hr cam, performer eps intake, and an edelbrock afb 750cfm carb. The car also has a 700r4 with a 3.55 gear.
Anyway, I was just wondering what it would act like on the street lugging around 1200 rpm with the old weiand 7525 single plane intake and a 575 annular booster demon?...
From what I understand the weiand 7525 is a very low rise single plane which unfortunately is not made anymore, but I think it would be cool to put it on the engine with the small annular booster carb. Of course what I would be going for is good low rpm manners with more top end than I have now...
So, anyone ever try something like this... opinions..
again no money right now just wanting to know other people's thoughts.

Thanks. I really don't have the funds right now, and if I do anything else to the car anytime soon my wife will kill me 
... I do want to do this someday if others think it would be streetable(which I know is tough b/c everybody's definition is different).

The 575 carb is goingto limit your top end. I ran a Victor Jr. on my 385 with older 190 AFR heads but a large solid flat tappet cam. I also ran an 825 Mighty Demon carb. It did not like to run below 2000 rpm but I ran it there sometimes. Just not a lot of power. The cam had more to do with it though. I have no problems running a single plane on the street, the low rise one you are talking about should be OK. I would run a 750 carb though.

I ran a Vic Jr for a while on my 406, and like Gordan, had a fairly large solid cam. Low end wasn't terrible, but nowhere near as snappy as it is with the dual plane. My cam tips 7000 rpms even now with the dual plane, so I was justified using the single plane I suppose. The cam you are running doesn't even get near close to needing a single plane, so in your case I wouldn't even go there. The gains you might see would be a few horse power, but the loss of low speed drivability, especially with an OD trans, wouldn't be worth it.
I guess in my opinion, I'd keep what you have, and try a slightly larger cam.

I've been running that intake for several years on a 355 w/ a comp 282solid. Low end torque (under 2k) is still more than adequate. I have no problem lugging around at 1500 rpm in high gear. Above 2k pulls hard. Here's my last chassis dyno run with that intake. Nice and flat torque curve.
