eBay LS Swap Headers - Test fit on a 67 Camaro

[Corey R.]

Looks like they clear fairly well. How close is that tube on cylinder 7 to the 90 degree PS fitting? It looks close. I have seen some 1st gen folks have issues with fitment and long term durability with the long tube headers (67Rally comes to mind).

What material are these made out of?

Its the angle of the photo. There is plenty of clearance there. I can verify the exact measurement.

They are stainless steel. Probably the cheapest type but we will see how long they last. This was more of an experiment, so I'm not worried about it.

I'm just glad to get the Dynatech's off the car. Those are a nightmare on lowered 1st gens.

I think I have these same headers on my Falcon (5.3 LS). It'll be some time before I get any heat in the headers, but overall, I was very impressed with the materials (flanges/thickness) and welds. I mainly bought them because the manifolds I thought I was going to use presented too many problems. An added benefit of the headers is decent weight savings. They fit the around the block and bellhousing like gloves . . .

I have been eyeing these up. Has anyone tried them?

Trying to get my buddy to give them a shot, as he has dynatechs as well with poor ground clearance. Shimming the tailshaft would help a ton, but he's running a t56 and it hits the tunnel. In the short term we are going to cut the collectors off the dynatechs & run a slip fit collector with a thin style band clamp.

Those Speed Engineering headers closely resemble the Dynatechs. I can see those still having ground clearance issues.

This the problem. On T56 tranny installs the tunnel needs to be cut to get proper driveline angle which also brings the header collectors level with the subframe and achieves more ground clearance. Also keeps the engine level in the engine bay and the rear of the engine parallel to the firewall and puts less stress on the motor mounts.

We have dynatechs on a 69 lowered 2" on Hotchkiss springs. Clearance work ok. I ran Hooker Supercomps on 2 cars and they tuck up nicely higher then the FBody oil pan.

Ya, he needs to raise the tunnel. We'll do it eventually. I raised mine last winter during a motor & subframe swap with the alston chassisworks cap. For now we'll delete the collectors flanges to the slip fit style. There's only a few scrapes on the header tubes themselves, but the collectors are ground down a bit. Its still going to scrape, but at least it will be on a flat surfaces vs a vertical one.

Hey guys, just as a side-not to this thread, you only have to raise the tunnel on a 1st-gen LS/T56 swap to be able to achieve desirable U-joint working angles if you are using the stock frame stands and swap plates to mount the engine. The Hooker 1st gen LS engine mounting brackets and T56 crossmember mount the engine and transmission lower in the chassis than is possible using the frame stand/swap plate mounting method and requires no tunnel modifications to install either a 4th-gen F-body T56 or T56 Magnum transmission in the car while achieving optimized U-joint angles. The Hooker Blackheart 1st-gen headers are designed around this mounting geometry and provide tight tucked ground clearance.

I have those exact headers going into a 66 GMC truck. They appear to be pretty well made. Welds look good and flanges are thick. I've had them bolted up and they align with all the bolts fine. I know they are knock-offs but was worth a try. I'll start a thread on the truck in a few days and take some pictures of them.

I checked the clearance and it's a little over an inch.
