Doug Thorley THY-324Y-C LS swap headers
 

Brand new set of Doug Thorley THY-324Y-C LS swap headers for 2wd and 4wd 67-72 GM Trucks (C10, K10, K5, etc.). Bought and mounted on my K5 but went in a different direction, so my loss is your gain. They have been mounted per the pictures, but are absolutely brand new. Bolted in nicely, but were almost touch my firewall. Didn't want to move my engine and trans of dent my firewall at this point. Fit great, but my motor mounts are just slightly too high. These cost $650 new. I'm asking $450 plus shipping. Still have all hardware, gaskets, collectors, and instructions.

Man, this is an awesome deal! I love mine in my 71! They fit and look really good. Good luck with your sale.

Re: Doug Thorley THY-324Y-C LS swap headers
 

They are awesome! Quality is great and they look killer. I'd make them fit, but I have so many other loose ends to focus on with my swap, that I just threw on the ls3 manifolds I had in my garage. If they don't sell by the time I have this running, I may try to make them work again.

What is the crossmember you used for the swap? What transmission? Do you have any pics of the passenger side?

Re: Doug Thorley THY-324Y-C LS swap headers
 

I used a Dirty Dingo 4x4 crossmember. I have a 6.0 with a 4l65e mated to the stock np205 location with the advanced adapters kit.

So the issue was the firewall being close? Can I get a shipping quote to 95982?

Re: Doug Thorley THY-324Y-C LS swap headers
 

I'm getting estimates of over $100 right now. I have to figure out why it's so high. The box would be pretty big, but this doesn't seem right.

Re: Doug Thorley THY-324Y-C LS swap headers
 

Best estimate is $80 for shipping. Let me know if you are interested. Thanks

Re: Doug Thorley THY-324Y-C LS swap headers
 

Thanks but I’ll have to pass at that price, good luck with the sale.
