Wheel Vintiques 60 Series Pontiac Rallye Wheels on our trucks?

[sick472]

I am looking at wheels which means that the project is getting closer to being done and really like the Wheel Vintiques 60 series Pontiac Rallyes so...

Anybody done this? They come in a 15x8, 5x5, with 4" backspacing, and will accommodate the 1/2" lug studs of my 72 C10.

8" may be too narrow for me. I'll have to see what my current roller wheels are. The 400 motor has about 350 HP with 307 gears...8 inches may just spin off the rubber too easily.

4" backspacing (in combo with the 8" width) may be too much. I'd like to widen the stance out closer to the fender edges (maybe spacers).

16 or 17" diameters might be better, but these don't come that way. I'd kinda like a taller tire than 15" rims would support.

Not to mention, my truck sports a Pontiac 400 motor so it would be fitting if these would work for me. I have plenty of research to do with this decision, but thought I would start here at the forums and ask for thoughts, concerns and experiences?

My other interests are the smoothies and the later model truck rallyes.
