I am still torn on what to do with my headers. I have a set of ProParts and even test fit them with good results.

But, I believe they are too small for my engine combo. I have heard they are a great street header, but for my combo which is race only, they may leave lots of HP on the table.

This is a 496" low deck with SR heads ( I have some CNC325's to put on later) STR-15 with dual 800's with a Jerico in a 68 Cuda.

I was hoping someone had run them or dynoed them against the pro-parts headers and could give me a comparison. The tube length on the ProParts are all over the place. Stahl doesn't give any info on tube length on their site.

This is a link to the headers.

I have used the Stahl fenderwell headers in the past.Without a doubt the nicest set I ever used.However the pipes were too long.Very equal but too long.We went faster with under the chassis adjustable Hooker Super Comps.Perhaps he will make them to a custom length or adjustable for your combo.

Mike,

The under chassis stuff probably wont work for me because I am running a Jerico, and had to use the stock type mechanical linkage (NSS Rules)

What was your combo back when you tried them? I am set up with a 496 and will be shifting at 6,800 to 7k.

why r u running 2 1/8 size?
really no need to run that big (unless you're over 528" motor?
i think you will lose bottem end torq
& hp up top
we have several cars running 9 with
bigger motors and 2" headers
i can see a step type header?? but unless you're
prostock , some crazy, there is no need to be that big on headers
i'm going to build a 500 an i very seriously considering 1"7/8 size header
i think i can build more hp & torq over the 2"
i have!
i know of couple cars running deep into the 10s
with 1"5/8 street headers!!

I was going with 2 1/8 because my engine is a clone of a friends. He picked up quite a bit switching from 2" to the 2 1/8". He is in an early B-Body in the 9.60's

I was more concerned about the tube length mismatch of my ProParts headers and was looking for an alternative. I figured while I was buying headers, that I should step up because of the difference it made on my friends engine.

Also because I will eventually upgrade my block and go bigger along with my 440-1 heads sitting in the closet hehehehe.

Dave, I have them for my Dart. If you want pics let me know and I will send them to you.

The only issue you will have is if you go to the aftermarket master cyl. You will have to move a tube around it.

That is what is done on mine.

As already mentioned, you don't need that large a primary IMO. Someone good can build you a set if your concerned about leaving something on the table. (The STR will do that by itself.) Check the ads on Racing Junk...I saw some companey posting custom builds for B-eng. A-bodies. 2" is the most common (cost-effective) option and more than adequate. With the set I just built, BS headed 451 "B" A-body, I doubt they would be a limit to 800+HP.

Tony I would Love pictures. I am using elephant ears, and have a rear/firewall bracket as well. I moved my clutch linkage some because of the pro parts, and I suspect the Stahl tubes will give me more room.

I have a two bolt MC that is re-worked for my Aerospace brakes. I am not sure how the sizing is compared to a stock one, but moving one tube will not be too much trouble.

Also how is plug access on these?

Ari, I will do it once I get home. I can not get to the site here at work.

EDIT: Here is a link to my Dart at bigblockdart.com I have some others that I will post but this should show you fit and finish. Note the tube being turned and rewelded on the driverside.

Dave, once you see the pics you will know if they will work. also don't do like I did. The tubes will fit if the motor is not moved back. I did a little massaging on my fire wall before I test fit them... I was an a-hole.

IMO, you are at the dividing line for 2" and 2-1/8". The average length of the ProParts is a little long for you, so if the 2-1/8 are closer to 32", I think that would be the ticket. Call Stahl and ask. Now if your combo is heavy (over 3400), small cam, low CR, etc. then the 2" might be just fine. Another gauge to help decide, if you are 3200 or less, and make enough steam to go low 9's and 7200+ rpm (finish line), the 2-1/8 should be the ticket.

I love the 2-1/8 x 32" x 4" collector on my 511 CID. I ran the ProParts 2" back when I had the 470 CID. Looking at my sixty foot times I don't think the 2-1/8 are killing any torque! LOL
496 is just at the line depending on combo/application.

Jim,

I don't know the final weight yet, but it is a CM cage, and will have lexan, fiberglass fenders, hood, bumpers and deck lid. I am finishing the paint to put it back together. It is a new build so I have no idea what the final weight will be.

Going to have plenty of steam and should be somewhere in the low 9's.

According to the Stahl site, suggested retail or list is over $1400. I would think there is someone in Texas that can build you a nice set of mild steel headers for that or a little less. If you are a member of the Texas Outsiders, someone there might be able to reccomend someone.

I'm Gumby dammit!

think they want to sponsor me??

Most people put too large of a header and never seem to pick up enough performance to justify the cost...You already have Proparts ?? then spend the $1000.00 or more on lightening the car or something else...but thats just my

those Stahl headers look a lot like Tubular Automotive headers except Tubular are 2"/3.5". With Tubular Automotive headers, clutch linkage can be in the stock location, easy to change plugs and good starter access. They were designed by Ed Hamburger and are supposed to be the the best flowing non-custom bb A-body headers.

I went from pro parts to 2.125 Stahls when I had the 451 although I also uped the compression at the same time but picked up a little over a 1/10th in the eighth mile. When I went from Stahls to TTI 2 to 2.125 steps it didnt seem to hurt it either. Pro Parts range from like 33" to 54" in length, Stahls are equal length and I think are 34" long, TTI's are not tuned but much closer in length than the Pro Parts. You will have turning radius issues with the Stahls, but they are a breeze to take off and on. Additionally, the Stahls are lighter cause they are made of thinner material, made very well but after a few years will crack and you will be repairing them often.

I wish those 2 1/8 equal length Stahls weren't so expensive I'd love to try them on my car. I have covers that unbolt, they cover the holes where someone used to have fender well headers, so they should bolt right on. I currently have the ProParts on my 500" low deck. I initially thought the Proparts were hurting my combo but after carb jet and air bleed tuning it picked up to a 9.82 at 136 so I don't think the headers are hurting now.
