Rectangle port intake on oval port heads.
There have been numerous posts of people using the factory dual plane aluminum rectangular intakes on oval port heads with good success.
With that in mind, would the same be true with a single plane intake?
Ran across an old rectangular port Team-G intake digging around in the garage that got me pondering.
I have a dyno mule engine of sorts in my car right now for the time being.
461cid, 781's, 230/236 @.050- .552/.555, Performer 2-o, 800 cfm Q-jet.
The performance is acceptable, but seems restricted and plateau's of sorts in the upper RPM's I believe is intake related.
I will be doing some track testing, between the 2-0 and a molested factory cast iron high rise oval intake.
So figured why not try the Team-G also.
To try and keep the experiment as apples to apples as possible I'd like to use the same Q-jet on all the intakes.
So the main question/questions is/are;
Running the Q-jet on the Team-G's dominator flange.
(Adapting a spread bore onto a standard square bore intake, leaves something to be desired in the flow path department in my opinion with the spread bore's large secondary butterfly size and would skew testing where the dominator flange would not.)
Would it be worth making an adaptor for the Team-G and adding it to the testing, or would it be overkill and a waste of time being a high RPM intake? (I can mill out an adaptor for 5 bucks worth of bolts and material laying around the garage.)
I know, put a Performer RPM on it, but that costs money.
I'd rather buy the crank trigger for the new engine, than another intake for this one.
It's a temporary engine and just thought about doing some inexpensive intake testing this spring before removing it.
