Port-o-sonic intake manifold?

Any thoughts?
Is it worth looking for?

I don’t need a single plane intake but I’d like to try one.
Just don’t have enough room under the hood for a victor jr.

Tongue intakes

Flash, what engine you have and why do you think you want to try one ? What kind of driving is your car used for ? The singles can help you make some great top end power, but many of us are best served with a high rise dual plane. LSG

It was a good intake in its day but I believe the ports are pretty small when using modern heads. Stick with the Stealth, RPM or Airgap as those can be port matched without issue.

At one time it was probably the best manifold offered for SBF.

I have one, NOS never been bolted to engine if you are interested?

Don't see them much anymore.

“Flash,

WOT fun!
Is that a good enough reason for you? 😁

I was thinking I could find a used port-o-sonic fairly cheap. Not worth it for me to buy something new. I’ve already got a decent dual plane manifold.

I always liked the question / statement: "Do you drive your car at WOT all the time? No, you don't." The implication being that building a boring engine to putter around town with is more nebulous than building one that is good at wide open throttle blasts, or that those two things are mutually exclusive.

My friend Tom used to run these on alky dirt track cars sometimes. He had one "experimental" 302 that spun clean to over 10k, putting out who-knows-how-much horsepower. They weren't great on the low end, but they come alive pretty good up high, and they won't give up till your bottom end does.

I’ve also considered getting a Weiand X-cellerator or a Holley street Dominator but can’t seem to find any for sale for a 302.
The port-o-sonic seems to have a strong reputation.
And I have a Holley 650DP that would look great sitting on top.

One of the problems with most single-plane manifolds on the 289/302 platform is how narrow the intake is. You usually wind up with 4 long runners on the ends, and 4 short ones in the middle, so your intake is 'tuned' to two separate frequencies.


I think the Parker Funnel-web, original Torker 289, and Edelbrock Victor Jr. are probably the best choices for most cars where you want a really hard top end charge. The Torker's small tapered runners are really good even for engines that aren't all-out dragstrip terrors.

leave the single plane intakes for the racing guys. if you plan on building motor that will in the low 12s, then perhaps a single plane intake is for you. otherwise stick with the dual plane intake.

Hmm... Low 12’s...
I like the sound of that 😉

Found a Parker Funnelweb intake on eBay for a very reasonable price. But I’m afraid it will be too tall.

If you want a low-profile manifold, you definitely do not want a single-plane. That's about on par with ordering a turbo Yugo.



For street use, a good Weiand Stealth or Edelbrock Performer Air-gap will deliver similar power, but better low and midrange than any single-plane.


Edit: With a carb. EFI prefers single planes.

Port-o-sonic = POS....... when used with a carburetor (on the street).
Generally no bottom end. Might be ok with compression, serious cam and lots of rear gear.
Had one on my '68 for awhile. Very soggy off the line.
Replaced it with a Weiand dual plane #8011. Big improvement.

Any "Parker Funnel Web" you see for a reasonable price is going to be the knock-off. Which isn't to say it's bad, but I've heard it flows no more than a Super Victor, whereas a real one would. And I think the Super Victor is shorter, but don't quote me on that.

Good comment. I a article I believe on porting intake manifolds and the subject was a old much loved 289 Torker. While good on it's day it was a restriction on today's heads. Taking it one step farther, how restrictive our intakes and exhaust systems to our set ups?
