Another intake thread

[gtxrt]

the best intake I tried was the rpm performer and the next best was a stock intake ported by Wilson. the ch4b and the regular performer made no difference in performance over the stock 1969 intake. the street dominator killed low end torque and did help after 3500 rpms. all on mild built 440

The M1 dual plane is the aluminum version of the factory cast iron. The CH4B is considerably different in height, cross sectional area, and naturally, volume than the factory unit.

Learned something new Personally I’ve liked the old Muscle Hustle catolog recommendations and worked well on the day on the stock cars

The 71 intake is no slouch.

@BSB67 says no it’s not. So maybe someone else can confirm it is or it isn’t.

Well the whole point of this thread is to use the dual snorkel.

Then the factory cast iron is just as good.

I’ve been thinking about this option too. Might just go this route.

The 71 intake flows as good if not better than a performer.

I think a lot of you guys are missing the point that this 71 factory intake is the best flowing 440 intake Chrysler ever built. It ranks in the top 5 when put up against the others mentioned here. I wish I could find that comparison article with the dyno numbers.

There was a FB post maybe FAST but there was a post where someone tricked out the 71 iron intake and looked really impressive for a reworked iron factory intake

Sure but at what cost $$$ ?

What was the et and mph of the unmodified stock intake and the CH4B?

Tried that. Didn’t work

What didn’t work? I was in the same boat. I insisted on keeping the dual snorkel air cleaner. It took a bunch of tries but I kept ordering different drop bases from Summit until I found a combo that worked. In the end I had to modify the one that I chose but not a big deal. Worked great
