67-69 LSx header spy shot..???

[chicane]

With SEMA just around the corner..... I know some of the guys are not going to make it this year....... so I though I would throw ya a little development/fitment teaser of our new LSx header:

Couldn't resist, Tom? :thumbsup:

Thats awesome. It is so cool to be building a 1st gen right now because there is new exciting stuff coming out all of the time :willy:

[Musclerodz]

That helps more than you think. They actually look like they tuck up within the sub. Cool.

[Steve1968LS2]

Nice.. that would bolt right up to my Spintech/Dr.gas exhaust :D

[Payton King]

Looks like a tri-y style (4 into 2 into 1)stepped with a swedge collector. Am I close?

[Teetoe_Jones]

Payton is correct. The header is a Tri-Y config, with a merge collector. The header doesn't do over the top of the steering box at all, so hydroboost is not an issue either. (Thanks for the mock up unit Paul@hydratech.)

I do not know if you have done any testing on that design compared to a 4 into 1, but I have heard that you will pick up about 30 ft lbs of torque at peak with a bunch under the curve as well. If you are going to produce these that is going to be a fantastic product. I know of no one building these on a mass production basis as they are usually a $2000 custom job.

Are you building these babies for A-bodies? Look very nice!!

Any chance they would fit a 2nd Gen? My '71 has an LS1 in it, with modified 4th gen Pacesetter headers in it. These would probably be worth some power over those.

Very nice looking pieces, in any case, and a very good choice of design.

Couldn't resist, Tom? :thumbsup:

Naw..... I guess not. But everybody needs a snack every now and then... :yes:

[XcYZ]

Tom, did you design these to work with an X-pipe of your design?

[chicane]

Tom, did you design these to work with an X-pipe of your design?

Unfortunately...... no. It would be real hard to fit a 3.5" true X-pipe under the chassis. The ride heights that we deal with would make it difficult.... but a drag car wouldnt have a problem. You could with our typical ride heights....... pull it off if you went with 3.0".

Another note..... you do not necessarily have to run 3.5" for the entire system. The collector however, has to be 3.5" but aft of that can be a size smaller. The recommended sizing is 3.5" to the front of the muffler and then 3.0" aft of that.

[Musclerodz]

Could these potentially work with the LS2 and LS7?

Mike

Basically, yes. There is no real difference on the exhaust side of the LSx line up. The engines are: LS1 = LS2 = LS6 = LS7. Where they differ is on the intake side of the LS7. The bolt pattern and spacing is different from the rest of the LSx line..... and the valve angle is 15* on the LS1/2/6 and 12* on the LS7.

The only notable difference is the flange of the LS7, it has a "D" port exhaust. We also have CNC'd flanges for the LS7 available now as well.

:unibrow: Good to know, now lets see some dyno results. There is a LSx motor in my future that will need exhaust.

Dyno results........ thats a good one, considering that we would have to take the engine package you are going to run and swap all the available headers onto it to see net results. These are not a barney bolt-on, off the shelf pair of headers. Every set of our headers are taylor made to the engine package and obviously every package will net different results. It really wouldnt be fair......

I guarantee these headers will make more peak power and make more power under the curve than any other header available on the market for an LSx swap into a first generation Camaro.

[Musclerodz]

I am not doubting ATS's abilities by any means. For some reason I like numbers and after seeing the thread on the LS7 header install, I was curious. I have narrowed my motor choice down to a stroked LS2 or stock LS7 (preferred) depending on availability and will require the sale of my '69 Blazer once finished to finance the powertrain package. I know you guys will be getting a call when I get a few more things ironed out and a little further along.

Mike

[protour]

Will these fit in an A-body, namely a 72?

I'd be up to see if it fits with my engine/tranny combo... 6.0l/4l80e. Its pretty far back in the engine bay. Camaro exhaust manifolds clear, 6.0 ones don't clear. They need to tuck against the engine but then have to go around the tranny.

I'm up for guinea pig status. :unibrow:

What company built these headers?

[Teetoe_Jones]

Proprietary info there Clint. We can't be givin' up our sources.
We could discuss it off the board though....
Tyler

[USAZR1]

Please explain why the manufacturer is a proprietary secret,Tyler. I didn't ask for any specs or dimensions on the pipes,just who made them.

[Teetoe_Jones]

The fabricator requests to be kept private due to the large influx of phone calls. They build headers for select race teams and companies, but generally doesn't do stuff for the open public.
Not a secret, just a source we searched long and hard for, and we want to keep a good relationship with our supplier.
As far as the public is concerned, ATS makes the headers. If you want a set for a particular application, we can have them made. I'm apt to use Shane's 70 Chevelle to make the next set.
Tyler

[USAZR1]

OK,I can understand that answer. What price range are you shooting for,Tyler?

[Teetoe_Jones]

Again, hard to say since each header will be completely different in terms of tubing diameter, materials, and options. I'll have a much better grasp of our general price range on these after the SEMA show.

[Rick Dorion]

Tyler, is this a service you also will/would do for regular small blocks?

[Teetoe_Jones]

We can do it for any car, any engine. The catch is that on ones we haven't made before, we would need the car to make them on.
Tyler

[Datsbad]

Tyler what is the pricing like? and how soon could i get them after i ordered them ?

i am willing to place a big order if you are willing to work with me . i have 2 69 camaros going together, so i would need double.

Are you building these babies for A-bodies? Look very nice!!

I want to see a set for a-bodies :thumbsup:

[Datsbad]

so did anyone get the pricing on these ?

[907rs]

so did anyone get the pricing on these ?

Pretty spendy for the SS version. Sounded like they'd be comparable in price to others for the mild steel set.

[Datsbad]

STAINLESS $3300, mild steel $2200 . :eek: :eek:
