Reply to "3785 Gets a 400 swap, fabbed 180's and fabbed mufflers"

While the pipes are still tacked in the car I start on the header collector tabs. I use a barrel bolt lock from the hardware store and cut it into the individual tabs. The metal is already formed I just need to bend the ends to fit the curve of the tube.

Here are the pieces all made.
The loop end fits a 5/16 bolt perfect. I will be using 5/16x2 stainless button head bolts with metal lock nuts.
I don’t think the nylon lock nuts will hold up to the heat.

I set them on the pipes using the bar from the kit to align them for tacking.

Here are the tabs tacked in place.
