Classic Inlines Performance out of biz? Recommendations 4 headers?

[PhilC]

Classic Inlines branded headers were not made by Clifford, Mike had outsourced production to another manufacturer. CI did sell the Clifford product years ago, but there were known clearance issues with Clifford's dual outlet header. I know, I have a set I bought from Clifford.

Unless you make other enhancements, add the 3/4 port divider, improve intake flow, etc., the addition of a header alone on the stock 200 won't yield any performance gains. You'd be better off retaining the stock manifold so you don't have to dump a bunch of $$ into a new exhaust system.

I have 3 good used manifolds, no broken ears, and would be happy to sell one plus shipping. PM me for details.

Good info. I musta looked back when they did.

I have the port divider with my header install and the single-out version. It was still tight at the frame/idler arm intersection.

Here's a couple pics of the manifold I have. You can see, in the fuzzy sense, the broken ear on the upper rear bolt-hole. It never leaked and I used a pretty thick washer to spread the clamping force gooder.

Attached pics shows the clearance issue with the Clifford p/n 53-2112 dual outlet header.

Comments from the .html file of a webpage I had up for years (now gone) dating back to 2007, "In an attempt to resolve the problem on my own, I removed the split style lockwasher from the terminal and replaced it with a star washer. I trimmed all the "excess" terminal and that gained me sufficient clearance to install the header without it touching the terminal. Even after that, I am only able to slip a matchbox cover between the terminal and #5 tube. Not even close to adequate. No modifications were made to the header whatsoever."

Note the clearance between the shock tower and outer tube, more than enough to have offset the tube arrangement for greater clearance at the starter terminal.

EDIT TO ADD: I found pics of the head before and after rebuild showing the 3/4 port divider installed and the "stealth" 200 installed.

Hello, Roger.

I like the way that you used yellow paint to highlight "FIRING ORDER 523624".

How did you and Phil C divide the center exhaust port? Is that something that inserts and is welded in place?

Thanks, Dennis.

I had my machinist weld the divider in. Some people just insert the divider and rely on interference fit between the manifold or header to hold it in place, but many who did this later complained of the divider loosening in the ports and rattling after use. I wanted none of that, and since the head and engine was being rebuilt anyway, ponied up a few extra $$ to have it permanently welded in place.

Wow, you guys are awesome... what a wealth of information and experience among forum members to consult for advice!

Luva65 and PhilC, thanks for the offers on your manifolds. I did consider a used manifold but I have had ten plus Falcons, at least five of them, maybe seven were inline sixes. I believe nearly every one of them had a cracked manifold, well, no, my first Falcon did not, it ran quiet, but most had manifold issues.

So when I thought it over, I figured if I buy an old used manifold it will only be a matter of time before it too cracks. I am still considering a used manifold though so I may contact you.

The reason I may consider a used manifold is that I prefer to avoid "Made in China" and if the retailers are offering such I may just avoid it. Next reason is I get to come see it in person and compare it to my own manifold on the car to make sure it is the exact one I used on my car.

I have a Frankenstein, A 64 Falcon that had a motor swap using a 200 inline six with toploader three speed out of a 70 Maverick (or so I was told) so I won't be sure what to order when I buy from an online retailer. I believe I saw two or three options for the 200 six manifold and I want the correct one. Buying in person can avoid the issue of getting the wrong one.

My only concern with a used one, as mentioned, is how long before it too cracks like all my other inline six manifolds on all the Falcons I've owned in the past thirty years.

I've already decided to avoid the header, too many question marks, too many potential issues and at this moment in my life I'm very busy and cannot afford a $600 plus expense for a manifold.

I actually have a port divider but I never installed it because I never took the head off, heck, when the clutch went I parked the car and it sat for eight to ten years with only an occasional run to keep the car from deteriorating, I rarely need to drive.

Only last summer did I finally get around to doing the job and as you may recall, I ran into infinite problems with inferior parts or the wrong parts being delivered, and then winter hit and the car sat some more. I actually finished the job this summer!

Then the car ran like dirt, a friend helped me rebuild the carb, and now it runs like a top. I bought "Mike's Carbs" rebuild kit and float, no issues, no complaints so far, thirty bucks for the kit with brass float.

I have been running the car around over the past few days, I forgot how much fun it was to drive, MUCH more agile than my V8 Falcon, and much slower, but not slow at all. Part of the loss of acceleration is because I geared the snot out of the car.

I have 2.79:1 rear ratio, 15 inch stock factory steel wheels with very tall HIGH PROFILE snow tires on back, 225/70-15 tires, maybe even 225/75-15 tires.

I built it this way so I could mosey on down the highway at 75 mph without the motor even breathing hard. In 2002 I took this car to St. George Utah, where I lived and worked, then when that job ended, to California for a visit, then drove it back to Washington, and highway cruising was wonderful, 70 plus mph where legal and effortless driving, unlike my V8 Falcon which is screaming its guts out with 13 inch tires and 3.25:1 final drive ratio.

Oh, the inline six returned 29 miles to the gallon from Seattle all the way to Utah, I measured at every fill up and that's the economy I got.

On two certified scales the car weighed 2430 pounds, and with the 200 inline six, that low a weight gets pushed along nicely with nearly 200 ft/lbs of torque and the measly 120 hp, despite the tall gearing.

With the original 13 inch wheels and tires, and original six cylinder rear ratio, the car would light up the tires from a dead stop without dumping the clutch as I recall.

I'll get some recent photos of the car on here soon. It's ugly, I rescued it from a junkyard in 2000, but it's a good car.

Replied to your PM. Primary difference between the OE manifolds is the 60 - 62 used a flat flange for the exhaust mounting surface vs the donut style for 63 and beyond. If your 200 came from a 70 Maverick, and the 70 manifold was used, it is the donut style.

Only other concern is manual/automatic choke, to me it wouldn't matter, but to you it might. If you have a manual choke, you can use either one. There are ways to make an automatic choke work without the heat tube (fab a heat stove) if you're so inclined.

I'll know later today which specific manifolds I have.

As with anything used, no guarantee future failure won't happen, then again it might last the life of the car.

I have a port divider, but rather than welding it in, which required brazing it with head still on, I added just a bit of weld to the center of the header so when I bolted it on this weld pushed on the divider. After many years the divider is still tight and using my custom hand-made copper gaskets there has been no leaks either. Can't do that with stock exhaust manifold though.

They claim the port divider improved the performance due to balancing out this massive opening between 3 and 4, which was different than all the other ports. But it has been 15+ years since I read anything about it, so what the actual claim was is a bit foggy. I'm pretty sure the design for the large opening was to help with carb icing, since they didn't have heat risers on the 6 in those years.
