LS Swap headers

[67rally]

I have a cheap set of eBay headers I used on my '67 Camaro last year. I think the flanges are warped causing exhaust leaks, and I'm in the market for a new set of headers. I'd love to be in the $5-600 range.

I liked the idea of the new Hooker headers, but I'm not willing to swap out my almost new Holley oil pan (1st version) or my engine mounts/trans x-member. The Hooker/Holley stuff looks great, but they came out with it a year too late for me, so I'm looking at other brands.

I posted this on LS1tech as well...

Has anyone used the stainless steel LS headers from Texas speed in a 1st gen Camaro here? https://www.texas-speed.com/p-4273-texas-speed-performance-1-78-long-tube-headers-first-gen-f-body-1967-1969.aspx

Looking for pics of PS box clearance as well as how low they hang or how tight they tuck in relation to the subframe. Thanks.

[67rally]

FWIW, I have looked at the Dynatech headers I have heard they have great steering box clearance, but I have also heard they hang down too low.

I know Doug's makes a decent set of headers, and would be interested in seeing how those fit on a 1st gen if anyone has pics.

I'm open to other suggestions, but I'm not looking to pay a grand or more right now.

[rickpaw]

I have Dynatech headers, and they hang very low. I have Hotchkis 2" drop spring in front/1.5" drop leaves back, and the headers are 2.5" from the ground. I'm in the same boat as you are now. Hookers set up is nice, but then requires to change everything out.

Rodney (RodP) has a set of Sanderson shorties and it allowed him to tuck the exhaust up nice and tight. I'm eyeing that set right now.

I have the same suspension setup as you.

What type of frame and motor mounts are you using? Also, what is you transmission down angle currently? Thanks.

[rickpaw]

I'm using the DSE mounts recommended by Dynatech in the header instruction book (forgot the part number). My driveline angle is 3 degrees. Had the car up to 98 mph with no vibrations at all.

I can take a picture or two of the headers when I get home from work.

Brent,

Here are some pictures of the ground clearance. I'll be very happy if I can gain 1 to 1.5" of additional clearance. Options I'm looking at are Sanderson or Hooker shorties, or Kooks/Stainless Works headers.

The tube routing is very similar to the Texas Speed headers you posted.

[67rally]

^^Ouch, those are low! Do you know how tall the DSE mounts are (i.e. what's the distance from the subframe crossmember to the engine)?

[rickpaw]

Not right on top of my head, but here's a picture. I'm guessing 1-1.5" from the picture?

I keep reading posts from people that saying the Dynatech headers have great ground clearance. They must have stock height suspension on their cars. I have to admit though that the headers do clear every thing else, other than I have to clearance the DS motor mount a bit as one of the tubes just barely touch.

[armourmark]

street and performance mid length. You will gain a TON of clearance and will not be giving up that much power on the top end.

[zamora7]

Stainless works fit great in my second gen, maybe a half inch below sub frame. They even included their own engine plates but they're a good chunk of change. They got great with 1 set back plates from car shop Inc

[wayward]

Lookup regal454 on this forum... He just got the new holley mid length for a 1st gen camaro... Amazing fit

Thanks guys, but in trying to stick with long tubes.

I'm considering the Dynatech's or the Doug's right now.

I have Doug's for the a body... Tuck up well but not good on the frame and the collectors point up... I have a request into there support dept now for response... I would do some quality research..

Mark (regal454) has a set of dynatecs for sale that is what he took off..

Yeah, that's a crazy angle. Are the pipes supposed to go up through your floorboards?

I verified I got the right part number... Thought I might have got a diesel truck thru the bed wanna be big rig kit...

But no... 67 a body ls conversion... I hope they make them good...

The collector angle on any LS swap header is usually indicative of the engine inclination angle that was used during the prototype phase of the headers (in most cases the collectors will be positioned level with the chassis frame), which means if you want the collectors level to the frame you will have to set the inclination angle of your engine to the same position as that used by the header manufacturer. By the looks of the collector angle you have, it's than likely they set the angle of the engine to allow installation of a 4L60-4L75e transmission under the tunnel without requiring any sheet metal modifications. It will go in, but as you can see from the photo it requires you to run a steep inclination angle somewhere in the neighborhood of 5 degrees.

67Rally,

I would recommend using Doug's #3337 headers with Dirty Dingo adjustable slider mounting plates, stock small block frame stands

I used them on my 68' with LS2 and T56 (using Speedtech/ ATS T56 crossmember) I ahve a Lee Mfg. Delphi 670 steering box and have great clearance aroung the box and ground / frame clearance

Very happy with everything

here are pics

Thanks. I hit you up for pics (by e-mail) a few weeks ago, and that's why the Doug's 3337's are high up on my list. How close is the #1 tube to the PS box. It looks close in that first pic, but it could just be the angle.

I have approx 1/8"-3/16" clearance, since I moved the engine as far back as possible with the adjustable mounts and not be right up against the firewall

here is a pic

[Chev67]

I have the Dyantech headers on my 69 Camaro LS3 combo and they are way low too. Any one try the Doug's Headers with Ridetech's Tru-Turn? I was considering Ultimate Shorties now. Anyone try them?

You may want to flip the motor mounts around (2 bolts on top/1 bolt on the bottom) so that the flange on the bottom. Like the photo of Ridetech Velocity Camaro

https://www.pro-touring.com/threads/40893-Ridetech-com-68-camaro/page3?p=372493#post372493

My understanding is that Dynatech used Velocity to develop the headers. My Dynatechs were hanging quite low, until I flipped the motor mounts around.

is there a reason you need long tubes? have you thought about shorty headers? to help the clearance

Maybe but I there is a big difference side to side as well... So I me pretty sure my set is really more of a quality issue.

If I use these headers I'll cut the collectors off and keep the engine set as is.. I'm currently down 3 and will work well with the rest of driveline..

[lblevins]

I run ebay swap headers I cut the crappy flanges off and put a set os thick 1 7/8 flanges and flare the tubes before flange install.. This is what I run on my 1969 Nova with a 427 stroked 6.0 cathedral port engine. Works great i've done several sets for local guys.

[67rally]

Yeah, I guess I'm greedy and want the extra hp. I feel like switching to shorties is just giving up at this point.

Between PM's, my thread on LS1tech, LatG, and here, I have acquired a lot of good info and will probably pull the trigger this week.

You must have ordered from a different vendor, or quality control is a little different in China. I have a few header threads going between 3 different sites, and thought I posted these pics here. But I guess I didn't.

Ground clearance isn't bad with the eBay headers.

Well, after a few weeks of researching, emailing, PM'ing, three different threads on three different sites...I had narrowed it down between the Dynatech's and the Doug's 3337's. I ruled out the Texas Speed because there just wasn't enough info on them, and I wasn't crazy about the design.

The guys from Dynatech were great with trying to help, but it's the same design as the Texas Speed stuff (still wondering if Texas Speed copied them, or if Dynatech is making their headers).

So I ordered a set of the Doug's 3337's (jwcarguy's pics helped push me to the final decision). My only hesitation was that they look identical to the ebay brand headers that I was looking to get rid of. In fact, when I first got them, I thought they were identical, but there are subtle differences in the tube design (i.e. the guys in China didn't do a perfect job on the knockoff). I installed them this weekend. I ended up moving my engine and transmission about 3/4" back towards the firewall and I'm very happy with the clearance.

Looks great!!

I am glad that the pics and info that I gave you helped in your build!

[68sixspeed]

Waking up this header thread rather than starting a new one, looking for what header I want on my 68 camaro convertible, ls3/480hp. I have kooks 1-7/8 on my LS7 and they fit good but hang down lower than I'd like. I would prefer to stay with a stainless header, based on the above info I am kind of ruling out dynatech and dougs due to the ground clearance.

Has anyone tried the flowmaster 814115? 1-3/4" stainless and ceramic coated? The other ones I am looking at if anyone has feedback, stainless works and American racing headers both have a stainless header but more around the $1k mark vs $650 for the flowmasters. thanks- Dan

Ground clearance was great with the Doug's.

[Motown 454]

I have ARH 1-7/8" Stainless on my swap. They are tucked up tight. Check the last page of my build thread.

Nice, they do look like they are a great fit.

[68sixspeed]

Ground clearance was great with the Doug's.

Based on your pics I would say they are similar to the ground clearance on the kooks maybe worse, not terrible but not great. Some of the others seem to tuck up tighter to the floor and barely hang below the subframe. You have 2" below the subframe.

[Motown 454]

Thanks only tight spot is on the pass frame stand and it will be trimmed.

[68sixspeed]

Quick note on the Flowmaster 1-3/4 headers, build quality looks good. But I only test fit the passenger side and it hangs down below the subframe about the same as the kooks on my other car or the pics above of the passenger side Dougs. Lower than I was hoping, I might have to get the American Racing after all..

[Vegas 69]

I've use the Hooker Supercomps on a couple builds. They clear everything and tuck up nice.

[68sixspeed]

Pics? :)

[BLACK DEATH]

So dynatechs are a no go then?
I have the hooker swap kit, but haven't bought headers yet.
Local guy has dynatechs for sale but if they hang low & I want to lower the car an inch or two in the future, I don't want to screw myself. But then lowering may not happen either anytime soon.

[Rod]

For a variety of reasons that involve physics, it turns out that long tube headers do the best job building horsepower and torque from mid-to-high RPMs. These are great for high-revving machines and Drag racing track terrors, but they do sacrifice some of the low-RPM power that most drivers depend on.

On the other side of the coin, shorty headers deliver more power horsepower and torque from idle to the mid-RPM range. This makes shorty headers perfect for your daily commute or hauling your boat up a hill.

Also note that sometimes short tubes can be easier to install and can add ground clearance

[jlcustomz]

Rod, not to be arguing with anyone here, but that's pretty much the opposite of what I've read on headers over the years, particularly for LS engines which most say go long or go home.

Of course I don't own a dyno to confirm that, but I did get knowledged design help on a set of long tube tri-y headers which I haven't had time to test fit & complete in order to butt dyno test against my crappy little short/mid length headers.

Engine to frame clearance & ground clearance usually always is more of an issue with long tubes, but if you do build custom fit there is a such thing as an inline 4 tube collector for ground clearance as an option. By the way, some dragsters these days are using tri-y headers, such as specified by Burns Stainless, which defy conventional design info we may have heard over the years.

[68sixspeed]

I will also try to add some pics to this thread when I can find them, I ended up staying with the flowmaster headers. Once I got the motor angle right by raising the back of the transmision the fit was good. Close on the steering box, but hey they all are. More ground clearance than the Kooks on my other car or the Doug's posted here. Pretty good quality for $650 coated stainless, including the collectors with the o2 bungs and extensions.

[oldstv]

It looks like most of these posts are dealing with the Camaro. Can anyone add advice from their experance on a 66 Chevelle? I don't mind using shorty headers if that will help with clearance but would rather go long if i have a choice.

Oldstv, I don't know if it will be useful to you or not, but I'm currently working on the development of the Hooker 1964-67 A-body LS swap system, which will include long-tube and mid-length headers as part of the effort. What engine mounts and transmission are you using in your swap?

Todd, I'm not sure, a shop in central fl is doing the swap for me. I wanted to wait for the system that you are currently working on to start this project but they had an unexpected opening in their schedule so I go in line. If you have any suggestions please pass them along.

Being that you're dealing with scheduling time constraints and the fact that I don't know any of the engine/trans/component details of your swap or your end goal, my recommendations will be of little use to you at this stage. Before you worry about headers, I would just be sure to ask the shop how they plan to deal with the two common issues that are related to the 64-67 A-body LS swap application, i.e. the clearance issues with the oil pan/tie rod ends and the difficulty of obtaining optimized U-joint working angles. If they are cutting your floor open then these become less of an issue, but if they are not, I would want to know every detail about how they are performing the swap for you so you don't end up with a non-optimized set-up that you'll have regrets over.

Todd, it is a 66 using a crate ls3 and a 4l60e trans. I assume they would use the new Holley -2 pan but I don't know about everything else?

I really want to use kooks mid length on my 67 F body LS7 swap. Anyone running them?
