Well, I'm glad you're around Karl.....
Why do i sit and think about stuff?
That lebaron i bought, thinking i will build a better chassis for the Fargo. Then move the 360 and body onto the frame. Power steering is the big plus.

I think my Swinger hass sprung a leak.
Good Morning All!
Must be the top tank, drivers side lol!
If you guys are talking V8 or /6 I can tell you Charlie here told me this, all engines need back pressure, when I had my 73 Challenger 340 car I had unbolted my collectors and tighed up my exhaust to get a time on my car, plus the cool factor of open headers at George Rays drag strip.
Open headers ran 8.69 to 8.90. Then I hooked my exhaust back up and it ran 8.10 to 8.20.
Charlie advised me to run my two 1 1/2 " drop pipes off my /6 to a 2.1/4" single pipe.
Glad I did, no drone at all and a bunch more power at 2800 rpm threw 5000 ram
Is this what you guy are talking about ?
Its still early and in my first cup.
Oops ,I got two super nice coffee t-shirts yesterday !! Thank you to who ever made that happen.
Swinger Sprinkler?

Thanks to @Old man ray
It's a 225 slant 6
Dual split Clifford's... 3" at the collector and 2" pipe back.

I once had a tri-y header for my Toyota 4 banger 4x4, was said to have great "scavenging". This quick article cleared it up for me what that exactly is and how it increases power.

Wow, ok, you have 3" coming off your two headers ? 2 " exhaust pipe, stock build ? Or shaved head and bigger valves ?

Could you set the Fargo on a modern Dakota chassis
Got that heater core in yesterday, ended up needing nothing to tack the studs on. Since they were the bottom studs and there was a slot/groove once I pulled the old clips out I just used this hardware, got lucky tightening them up with an allen wrench being held by bracing. No leaks and it makes hot air, have to put three ducts under the dash today.

I took my two 1 1/2" split manifolds to a single 2 1/4" And a stock 318 muffler.
Sounded , started and ran great, @Charlie.s was my go to exhaust guy, back pressure had to be spot on. Running a single was great advice.

it has a purpoise
Calvin Elston was often pushing guys to size down. He had a rule of thumb posted on his blog (now gone). Instead of thinking about pressures, focus on velocity and flow. The most important goal is to keep the exhaust gasses moving away from the exhaust port.
So Charlie was right, but the description might be confusing. When the header's collector flange is open to atmosphere, that 14.7 psi trying to push up into the header.
Gotcha...
There's no dyno sheet in the documentation that I have. Just the clearances and cam sheet
Good compression , lets get @RustyRatRod in here to look at the valve size , and duration/ lift.
I would test drive with the 2 inc pipe with no muffler, see how it pulls, but I think @Charrlie_S would be the man here, let him know how you want to use your car, race. Street stop driver. Between him and @RustyRatRod you will get the answers you need, sorry.. tec is not my best feature.

I will give Cheryl two hugs and Craig just one! Hah! Wear your sunblock today boys! She is gonna be toasty! I remember one year when you (TMM) were sick as a dog at MITP, you powered thru. Once you pop the trunk today all your troubles and sleep issues will fade away! Have a great time!

Wow just wow!
I would hook them up to one pipe, two pipes, two mufflers seem like a little much for what you/we want to use these great engines for, trust me, it will sound unpleasant with duals i think..
I tried a 3" X pipe on my Barracuda when it still had 340 manifolds on it. I do not have back to back times on it, but my conclusion was that it was contributor to the lack of torque and difficulty with getting a decent idle. Now that car has headers based in large part on Calvin Elston's recommendations.
Calvin Elston calls the gas flow "king" and explains it here:
"What is [exhaust] Blowdown Length?" p.2
He's been pretty generous in sharing his experiences. This is one about merging to a single tailpipe.
Flowmaster Outlaw muffler - anti-reversion? - Page 3 - Speed Talk
He done some slant sixes. He took down his website, but maybe I can find some pics because a few years ago I was emailing with Lou about them

From what I’ve seen, the X pipe is very location dependent, too far from the collectors and it becomes a hindrance, too close and it also becomes a hindrance.
