Intake For 396

Mild 396, small heads, nice driver has DP on Stock CI intake w/adapter. I’ve always thought adapters created all sorts of turbulence. Agreed?

If so, is there a decent (non-Edlebrock) al intake that we’ll fit under 69 Chevelle hood ?

I’d like to use a Winters re-pop. but they won’t work w/little heads ?

Or, would I notice any difference between adapter and Holley intake on a “sporty” driver ?

PS, I don’t want to go to big HP al heads on this car.

Thanks

Re: Intake For 396

I have ran adapters on stock iron intakes and made more power.
Not a deal breaker at all in my book.

I have also ported the guts out of the plenum on Q jet intakes and picked up 20HP at the wheels on mild SBC.
375 crank HP kind of deal.
Porting the Q jet plenum made it to 10HP less than a Performer RPM intake.

If you are not going to use the iron intake you might as well port it and try it out.
Just a little time and a few bucks to do it.

If you do get froggy I have found a stick welder cranked up with some gouging rod or just whatever rod you have will gouge the plenum guts out 50X faster than you can grind it out.

Use cooking spray or antispatter spray in the runners to make cleanup quicker and easier.
And do not gouge all the way .. Leave a little to grind with the grinder so it finishes out nice.

Re: Intake For 396

You can use a rec Winters intake on peanut or oval port heads just use rec gaskets it will work just fine. Another option is Chevrolet performance intake they are very similar to RPM intakes and of rumor is right Edelbrock makes them.

Personelly I like Edelbrock intakes but they dont look oem.

Curious what the issue is that you have with Edelbrock ? That would be my first choice.

“I have ran adapters on stock iron intakes and made more power. Not a deal breaker at all in my book.”
Thanks Jeff, I would have never guessed ! You might have the answer for a merely sporty car.

If I used rect port Winters intake feeding round port little heads, wouldn’t there be a serious mismatch ? Like Holly to adapter to Q jet intake ? (Which Jeff says isn’t so bad)

Since someone asked, IMO Edelbrock is for cruisers, no serious equpt. . When I see Edelbrock on a car, I immediately discredit it as a serious performer.

Names I look for include Holley, Brodix, AFR, Comp Cam, Lunati, MSD, Howard’s and plenty others.

^ MO and it’s worth what ya pd for it 😁

Thanks for the replies and if I paint the carb adapter Chev Red, maybe I’ll forget it’s there 😁

Re: Intake For 396

x2 on what Jeff Swisher said.

I cut mine out with an air saw.
I also ground an adaptor to make a spreadbore open spacer instead of cutting the plenum divider.

Re: Intake For 396

I believe Mark Jones had a measure of success with iron intakes on some of his "hybrids", if I remember correctly they made some surprising power and torque...might want to check into it.

My Edelbrock will make you think differently.

Re: Intake For 396

I have used Torquer 2 intakes under stock 69 hood. Most of the older styles should work.

Yes, the ones that are under the carb. Tapped them for steel pipe plugs.(see pic.)
Left the cross over between the heads open.


I have a Eddy 2-o (like the one in the pic) on the engine in the car now, that I will be testing the iron one against after the track opens.

The Eddy 2.0 is still a good intake. Also take a look at the Weiand dual plane intakes for BBC's. The 2 GM intake mentioned above are just re-badged Eddy rpm intakes and your paying for the big GM bowtie on it, that's all.

Brodix HV 2017 is a low profile intake. I don’t know how the port and plenum sizes compare though.
