350 timing

I need the coreect timing for a 90 Suburban, 350, throttle body, electronic
ignition. Can't seem to find a vacumn advance tube, any hints?

There is no vacum advance, it is electronic. THere is a connection on
the fire wall that you disconnect when setting the timing. Stock is
TDC but I run mine at 6 BTDC (a 89 Burb) and have for year as it runs
a lot better and gets better MPG too but the tade off is you have to
use 89 octane or better too which I always have anyway. I have gotten
up to 19 MPG on the hiway with my 4x4 model at 65 mph with A/C on so
setup and fueled.
