Long Tube Headers Installed

[Pure-Juice]

I have used this forum countless times researching parts and tips while working on my truck. Thought I would pay it forward and help anyone out there looking to install long tubes on a SBC lowered truck. Pictures always help so I included a bunch of them.

After all my research I decided on Doug's Tri-Y Headers, PN: D371Y, $663 at Summit. Shipping was fast and parts arrived very well packaged & undamaged.

Passenger Side - Very easy install. Plenty of room to spare. Don't have a starter yet but planning on a mini type starter and should go in without issue. I have Dart Iron Eagle Platinum heads with angled spark plugs and there is no fitment issues.

Driver's Side - Header fit but 2 of the tubes were right up against the frame rail. Used a dremmel tool and removed approximately 1/8" of material. Definitely a tighter fit but I think it's going to work out fine. No issues with spark plug clearance on this side either.

I understand Doug's Headers is the original Doug Thorley company and changed names after a divorce. From what I can tell, his products are excellent quality.

Hope this information helps someone out there looking to do something similar.

Those look great! Can you show how low they hang down from the frame?

Plenty of clearance and the reason I chose these. I have 5.5" of static drop in the front although truck is not at the finished ride weight yet.

What about the clearance on the driver side lower control arm to header pipe? If you can fit more than a quarter in there, I think I see these headers in my future! Thanks for the pics, they look great!

Looks perfect, thank you so much for the pictures! Looks like I’ll be ordering a set!
