Re: 1989 Suburban 2500 Full L83 6L80 build
Also I should note that with this configuration, even when the timing seemed crappy the ECM was reporting I was getting about 20 mpg. usually more, but right around 20. That is something I didn't expect and maybe the computer is off just a little bit but even so I'm happy it's not the 12 I was used to with the big block.
