Hi!

I am sure that there would be some modifying, but would these possibly fit in a 99 suburban with the vortec 350?

I would love to free up some power and gain a mpg or 2.

has anyone done this to the older style truck?

thanks

They will work. I have them on my 99 OBS Z-71. They work great!! ...JohnB

 

yeah they should work no problem you might get a nelson harness i hear they work wonders as far as ease of installation
