Best streetable SBC intake manifold? What is the best carb intake manifold for a small block Chevy. Something that can make big power and streetable. I'm thinking of getting a intake manifold that will support a lot of power for future modifications (maybe 900hp or more). I would appreciate anyone's suggestion, thanks.

For good streetability, the Edelbrock Performer RPM Air-Gap dual plane is outstanding, but with what it sounds like you might be doing, go with a Super Victor or Victor Jr single plane.

ahh i see, so how does the single plane and dual plane affect the power curve?
Would the Victor hurt performance if you are making less than 350hp? I was thinking about getting big intake and run it till i get my other engine built. I don't know if this is a bad way to go.

It is like this, if you have a small stall about 3000 RPM or less, the RPM air gap is the right one, if you are going over 7000 RPM or stalling above 3500 RPM where the low end doesnt matter, the Vic Jr is better. And for all out, the Super Vic is the best.

Then it looks like the Victor intakes are for top end power. Just read edelbrock website found out they make power at 3500 to 8500+ rpm.
Thanks Zones89RS and Supermouse4
Im gonna keep researching see what else i can learn, before making the purchase.
I saw the Toker II intake how does it compare to the Air-gap? More off the line power? Is it possible to make big HP numbers with a Toker II?
Would Super Vic be ok to run on Chevy 350 as temporary intake to daily drive? Im guess it wont because there wont be low end power. Has anyone done this? is it real bad and not worth attempting?

Vic Jr for moderate power.... Super Vic for a lot of power.......... I think it is safe to say that with 900hp the Jr will choke it out.
On the 350 question........ if you plan to go with a Super Vic at some point get it and try it out.... if you don't like it put it on the shelf for a while....... you can find used Vic Jr's out there and I am sure you cna also find used Super's also.
The air gap's though are a tdime a dozen these day's and can be found at almost any swap meet. For temorary use I would get the cheapset intake possible that works for your combo...
When making power on a small block based motor I would not use anything but a Super Vic unless I went sheetmetal but even there often the added cost of the sheetmetal intake is not worth the added power.

It sounds like, as others have suggested, that the RPM Air Gap is your best choice for the current motor or a street thumper.
Once you build that big bad motor you'll want to go SuperVic if you are really shooting for high-rpm 900hp, probably ported to hell at that point too.
One thing though, your handle is LT1? Everyone here has been talking gen1 SBC which you can definitely make these intakes (there is an LT1 RPM air gap) work with your motor but there are some mods (blocking the thermostat housing outlet, closing the distributor hole, and some re-drilling of the holes for bolting the manifold to the heads. If this is for the firebird, disregard.

Generally, dual planes make more torque down low. Single planes make more torque up high (horsepower).

well i was going to use the stock 350 but decided to tare it down and start building it and keep the 307 engine thats in there now. So i'll be running the RPM Air-Gap on the 307 for now. Anyone know what temp. thermostat i should use?
UPS just dropped it off today.

So your asking basic ? about intakes and making under 350HP but your shooting for 900HP
I think you should buy a new intake in a few years when you get to that power level. If you are serious about the 900HP than the $200 for a new intake will be so insignificant to your total budget required for the big HP build.

Yup your right tittan1500 thats the conclusion i ended up coming to.
Initially i thought maybe i could by a bigger intake and hang with it till i got to the point of using it, but ends up being a bad idea. I would have low performance and crappy driveability just cause im trying to take short cut.

I believe just one of them, but I've heard bad things about the o-ring so I always just run the gasket. I have to admit, I've never tried the o-ring so it could just be internet chatter.
Nevada, sounds like Summit. Man I love them.
