Cool to see some testing with a near stock engine rather than a full out race engine.

Thanks 'H-Man',

Gives a better view of Intake Performance with 'stock engines'.

The 1967 383/325 HP Engine is built to 'stock specs' {Blueprinted and Balanced}.

Only change on the 1967 Satellite, the tires.
* Front ... GR70 x 15"
* Rear..... GR60 x 15"

Edelbrock Performer #2186

Design > Dual-Plane
Profile > Low-to-Medium Rise
Height > 4.00"
Carburetor Base > Spread-Bore 'Split-Divider'
Throttle Bore Size ... 1 3/4" x 2 1/4"
Port Dimensions ...... 1.14" x 2.12"
Weight ................... 17.6 lbs.

Best Performance....... 14.01 @ 99.58 MPH

Cool test. It might be interesting to start stacking spacers. Performance seems to have a correlation to rise height. Is the RPM going to be tested?

 

[HawkRod]

Interesting. So with the exception of the first (63-67) manifold, all of the times are within 0.05 seconds of one another. But, the speed through the traps of that manifold is the highest.

At a drag strip at with this level of performance, I would almost call the ETs equal due to driving conditions, etc. (except maybe the 63-67 manifold).

So far, what I am getting out of this is that if I buy an aluminum intake for my original 1970 335HP 383, all I am likely to do is save a little weight up front.

Am I off base? Thoughts?

 

[rumblefish360]

That's what I think. Conditions change day to day, hour to hour. The Performer is equal to the factory set up. Now the question is, can you tweak it/carve it to perform better than a likewise tweaked/carved OE intake?

 

[monaco66coupe]

as we can see Chrysler built it a certain way for a reason.

Correct

The Edelbrock 'Performer' Intake had a slightly better 'throttle response' than the {1968/1969} and
{1970/1971} 'stock' Cast Iron Intakes.

But, the 'Performer' was only {.03 to .05} quicker in the 1/4 Mile during our Test.

There is a weight difference of {21 lbs.} between the 'Performer' and the 'stock' Cast Iron Intakes.

Overall > We were 'expecting' at least a {-.10} quicker Elapsed Time, as the 'Performer' is taller in height by {+.56"} and lighter by {-21.0 lbs.}.

Weight
* Edelbrock Performer #2186 ........ 17.6 lbs.
* 'Stock' Cast Iron Intake............... 38.6 lbs.

Is the DP4B up next, along with the RPM?

Can we open this up to the comparable Weiand, Offy and street dominator as well?

 

[rumblefish360]

Nice idea YY1. Most mags only cover the Edelbrock offerings.

 

[Photon440]

Any way you look at it, low 14s is pretty respectable for a nearly stock set-up. :app:

YY 1,

You have to remember, that we're only running with a {Carter AFB #4999S} that came thru on
the 1967 383/325 HP 'Automatic Transmission' cars.

Primary ...... 1 7/16" .... 1.186" Venturi
Secondary... 1 9/16" .... 1.313" Venturi

These 1967 Carter AFB's were rated at {566 CFM's}.

Intake Manifolds up next;
* Weiand Action-Plus #8008
* Mopar M1 Dual-Plane #4529117

 

[YY1]

Point taken.

I see the Action Plus is up next. That should be fun.

DP4B should still fit the bill.

The M1 might also be overkill if the RPM and Street Dom are. .

Let's not forget that in Stock eliminator trim these stock intake manifolds go very fast. There are no doubt better manifolds but the stock intakes are fine for alot of cars and the gains are really minimal with a pretty mild engine.

Correct,

With a 'stock built' Engine and stock Carburetor, many of the Cast Iron Intakes do an adequate job.

Note; The Edelbrock Performer #2186 is listed as nothing more than a 'stock' OEM Replacement for the Mopar 383, offering some improvement in 'throttle response' and slightly better Torque in the low-end RPM range.

Overall, the Edelbrock Performer Intake had a 'net gain' of {+3 HP or 1.3%} at the rear wheels over
the best 'stock' 383 Cast Iron Intake {#2806301}.

 

[hunt2elk]

Great thread. Wish you were closer to me as I have a RPM sitting on my bench that I wouldn't mind bolting on your motor and seeing the results.

That's what I was hoping to see. I'm sure 440 Cuda's got one laying around somewhere.
