Header Repair/Refurb 2010 Chevy Camaro with a Big Block Part 1

I got a set of headers in for repair and shot a video of how I tackle this kind of work.

I really liked the trick for getting 100% weld on the bottom of the tube near the collector. I've always hated doing header repairs for not having access to weld stuff. I will definitely use this one in the future.

Thanks for sharing your header tips. I was blown away by the jig. I will be subscribing to your channel.

Do you have any photos/info on that big block gen 5 Camaro? Don't see too many of those.

I really enjoyed the video. It looks like you had your smartphone sitting out streaming the video - what's your setup for that?

I get excited every time I see a u-bend cutting or marking jig. Here's one Jaysin made that's pretty slick:

You set the U-bend over the center circle and position it at the angle you want to cut and then push it through the saw. If you want to do another size of tube or another radius of bend all you have to do is cut out another alignment circle and bolt it to the slide because the slide stays centered. It's an MDF slide with a piece of sheet metal screwed to the edge which guides along the edge of the band saw table. I pre cut the slot the band goes through to cut the part with my skill saw so that the blade would have some clearance. Sorry I don't have any complete U-bends to show but I thought about taking the pictures at the end of the day.



I threw a 90 on it to give you a better Idea.

Nice work/video. How is the steering shaft going to clear now?

No more than what I said in the video. Car was bought new with a V6 before the V8's were out and made into a drag car. Current owner took it on trade and is making it a pro touring style car.

GoPro Hero 3+ with wifi and the smartphone app.

Supposedly the motor was not in the car straight and now that it is straight the notch is no longer needed.

Thanks for watching guys. Part II will be along soon.

Pretty good video showing what dents do to Headers. Might surprise you! https://www.youtube.com/watch?v=azPKIjxmmdU

The flip side to this is I have seen a set of Box headers on a 400-inch SBC give away 50 HP to the Dyno headers and require a completely different spark curve.
I will admit that I am surprised at their results!
Interesting to say the least!

I wonder if the headers are sized too large for the motor?

If you watch the Engine Masters series you will see an episode where they try different configurations. There still is a science to headers. They just wanted to see if denting a tube would cause any horse power loss. David F had a set of expensive header thrashed to fit into a motor swap last year and he was concerned.

The Vid just shows that a good flowing header still flows well even with a little dimple and maybe even an uneven inside weld.

My thought is that if the headers are too big, then bashing them in will have less effect than if they are the right size or too small. I enjoyed thebvid and will check out the rest. Thanks for the response.
