231 Intake Manifold any good?

I have searched but no joy.

I read an old thread that mentioned the 231 intake and carb,
was a bad choice over the 225 setup.

I just freashened up a set from a donor 231, to bolt up today.
And then read this ,any thoughts on this being a bad idea?

If there is a thread on this would appreciate the link.
I couldnt find anything, but...

 

I have a 231 intake from a oddfire 77.
And it bolts up with the 231 gasket.
got that info here

I read a thread somewhere else where someone who should know, take with a grain of salt.

That the 231 intake and carb were bad performers compared to the original 225 parts.
i have been assuming the larger 2v carb and intake was a smart choice now this has me woundering if I am shooting it in the foot...

 

Well best info so far seems to imply that a 231 went to dual plane intake at some point and then of course you lose some low end torque.

This maybe when they went evenfire which wouldnt fit well ,if at all anyway.

I have a single plane from my donor car75 oddfire skyhawk.
The carb is bigger, still 2v, still very simple ,compared to 4bl.

I like the EGR in theory.

Should be fine I think figures you allways find something to make you stop right before you bolt it on.

 

Haven't seen a dual plane manifold from the factory on a 231 yet. Doesn't mean there wasn't one but I know my '80 231 isn't and the ones I've taken apart weren't. Nickmil

 

Yea I wouldnt know on the holly.
Done lots of GM and Edelbrock but no holly.

I made the switch because the original was shot.
Just didnt want to go backwards performance wise.

And read a thread that said they were garbage and it made me start to think to much..

I think it will be fine...

 

Thanks for the moral support.

Its going in now.

Wont start till spring but anyway 1 more thing done.

 

The difference is the ports in '79. pre '79 has "lowport" heads and the '79 and later have "highport" heads.
A '79 and later manifold can be bolted onto a pre '78 with the '79 gasket.

What it comes down to is the '79 heads flow better than the '78.

As for the stock carb, loved the one I had on a '78 stock 231. Yes, all the emissions and excess vacuum lines were plugged but was a very nice trail engine that got good mileage and would run a weird angles.
Then I got stupid with a Al intake, big cam, and holley 425cfm carb. BAD IDEA. I'd stay fairly close to stock for a cam, stock intake and if you must change to a holley, first choice would be a 2bl, 350cfm or 390 4bl, heard 500cfm 2bl work good but seems a bit much for to me.
