Stroker intake question and guidance, mainly guidance.

Good news! There is t but 1’current intake for the small block Chrysler being made that can flow the amount of air to feed the heads. All intakes will have to be ported to keep up with the heads. The only intake worthy in cfm flow would be the Indy intake. We will see how the TF intake does. It should do well since there designing it for there heads.

Other intakes that will do well unported would be really any large tunnel Ram that used to be made.
Holley Strip Dominator funnel ram or the M1/TR.

The cam duration points to a dual plane. A single plane could be used if you lost a 6-8 indeed pounds. Not joking here.

The single plane is doable. No doubt. You will loose some low end torque but gain up top. It will be a wash on the strip. I’d bet the DP would be the winner.

So the only thing left to decide on my engine is intake manifold. Bear(bare) with me on this over asked question? This car will be 95% street driven. Maybe a 1/4 pass or autocross once in a while. But it'll mainly be a driver, cruiser and canyon carver through the mountains.

So we'll start with some specs.
'68 barracuda notchback ~3200-3400 lbs
currently 3.55 8 3/4. This may go to 3.91's in the future
42RH trans, 3000 edge converter
6,000 rpm range
414(360) 4.06 bore
4" Molnar crank & rods, Mahle pistons -16cc 1.0,1.0,2.0mm
11.04 comp
Mopar purple .557(.594 w/1.6) 252@50
1.6 rockers
Trickflow 190 heads
Holley terminator EFI

Options
1. Mopar M1. I have a stock one on hand, along with a 1" 4 hole HVH spacer. It has pretty small ports and I feel this will need to be ported and blended in order to feed the trick flow heads. It is also a spread bore and I would consider epoxying the flange and recutting to a square bore.

2. Edelbrock RPM air gap. I'd probably buy it from Hughes with a street/strip port already done. Not sure if this intake can support the head CFM? This will need the plenum divider cut in hopes that the EFI will receive a decent MAP signal. I feel this is my best performance option but my main concern is with the EFI. I've installed and had trouble with vacuum signals on dual plane intakes and distribution.

3. Trickflow. Ed at Trickflow said these 'should' be available by August. This could extend months if it doesn't go well though. Their heads kept getting pushed, so who knows. I would love to use their intake but just can't wait that long.

Obviously I'm looking for max torque and horsepower. So, I need an intake that can support the airflow that the heads need. However, not outside of my operating RPM range. So here I am...

Thoughts?
