Cheap Headers - 12/18/13 04:36 AM
Does anyone make a cheap (around $165) full length header for a 1969 B body with big block AND...power steering.

According to the Doug's site, cant run them if you have an auto with column shift, which I have.

They will work with power steering. You may have to make a couple dings for clearance but the cheapies will work. One way is to use a c-clamp with a block of wood on one side so you don't mash them up like with a hammer.

They have the same really thick, antiwarp phalanges

Doug's headers have finger bones?

Quote:You are joking, right? WHY? What the hell do you expect to increase? Per dollar wise, Head aches, fitment issues, burnt plug wires, exhaust leaks, starter fitment issues/burn out. SERIOUSLY? What the hell do you expect to increase? What is your primary goal? Do you realize that headers actuall only increase HP by maybe ten or fifteen over stock? and THAT does not include Factory HP manifolds? Factory manifolds are almost as good as headers, with out all the hassles. WHAT on Gods GREEN EARTH makes you want to swap them out for HEADERS? Are you crazy? Seriously. You will never ever ever see any increase on a street motor. You will invite yourself open to a host of problems with headers. WHY? Why would anyone make this boneheaded move? If you want noise, get some Flowmaster Mufflers and be done with it. You can't possibly be serious. READ UP ON IT.
I looked at sites like Jegs and Summit, they had a few from 139 to 175 so I just piked around 165. Only problem is they wont work with power steering. I have some HP cast exhaust manifolds but dont really want to use them.

To those that think manifolds perform even in the same ballpark with a decent set of full length headers: You're wrong. No other way to say it. The dyno sheet above says about 20 hp & 25 lb-ft.; and thats on a motor that looks like its only making 320 hp. Immagine what the falloff is on a motor flowing enouth to make 500. I'm guessing its in the range of 40 horses.
Any race car you see that runs manifolds does so either because: A) class rules. or B) They like the look and are willing to deal with the lost performance. On most any typical carbureted V8, exhaust manifolds are the single biggest performance bottleneck in the equation.
If you don't like headers because you're experience is that they all leak and create problems; you likely aren't much of a Hot Rodder. A good set of headers properly installed (yes, it may take more than just bolting them on...) should not leak a bit. If you're having issues with burning plug wires: address the issues! its called Hot-Rodding, and it may take some ingenuity (thats the FUN part!).
Now, if you want to run exhaust manifolds and get the max performance out of a stock package (Pure Stock & F.A.S.T. guys are great at this), then thats another conversation all together. But to say that manifolds perform on par with a good set of headers is just plain Mis-informed. (and yes, I'll include the vaunted HP manifolds in that statement)

It would be interesting to dyno an engine with manifolds and keep swapping cams till you found the best one, then dyno the same engine with headers swapping cams till you found the best one....How far off would the best numbers for each be?

Just remember all these fancy Hemi's today still have manifolds. For the price they are the best option.

The modern Hemi engine uses a manifold that is a close copy of a shorty header. And it will outflow an old log style manifold by a lot. And every header manufacturer still sells a bunch of headers for them and have proven gains. Any header design that offers a performance increase will help make an engine more efficient, which gives more power AND fuel economy. Maybe adding 10 horsepower on a low performance engine that only puts out 230 horsepower doesn't mean much to some people, but increased efficiency should .

At what cost though?
$750 for a set of TTI's to add 10 hp seems stupid to me, as an example.
$159 for a set of Summit headers that embody all the worst qualities of a header again seems stupid to me, especially if the gains are minimal.
It's all a balance. If I were to put a 5.7 Hemi in place of the 273 in my Cuda I would bet the improvement, even with manifolds, would be substantially more than putting the best headers ever made on that 273.
If I were to build that 5.7L up to the point of maximum performance then a set of $750 headers makes sense, for an otherwise stock 5.7, no.

Testing manifolds against headers on a high horsepower engine seemed a little of to me. Thats why my dyno comparison was done on stock 360 with a very mild cam. Headers were still worth a lot compared to even the best manifolds I could find.
But I missed it on the 5.7 having logs. My bad there.

The summit ones are basically Hooker headers...

Now we're comparing header gains to an engine swap that uses current technology. I bet you dont find a modern hemi with computer,harness and all necessary pieces for the swap for anywhere near the cost of TTI headers.
For what it would cost to do all the swapping, I could build a nice engine that would perform better with headers.
Besides the O P asked about cheap headers, not TTI.
Headers are a proven provider of milage and performance gains. Feel free to not use them. Its a free world. A lot of guys dont like to improve their cars and think a carburetor designed for 70's fuels should run good today and points ignition worked fine 40 years ago.
Then there are people that dont believe in electricity either
