71-87 C10 is 5-lug.

What's in those images looks like it has the initial C10 'HD' rubber-lined steel bushing that threads into the a-arm (63-72).
73-87 C10 trucks/Burbs had 'press in' car style bushings.
73-87 C20/C30 had the HD rubber-lined steel bushings that thread into the a-arms like the 63-72 trucks but are 8-lug.

Building a small, high rpm engine with the perfect bore, stroke and rod ratio is very impressive.
It's like a highly skilled Morrocan sword fighter with a Damascus Steel Scimitar.....

Cubic inches is like Indiana Jones with a cheap pistol.
