Well the firing order for a 97 surburban 350 is 1-8-4-3-6-5-7-2
for the distributor, get i belive a 15/16" socket and ratchet or bar and turn the crankshaft till cylinder #1 is at tdc. then when you slide the distributor in check to see if your on or off and adjust till your on time, (remember some caps say cylinder 1 on the ie. left corner, but the rotor has to be in the right corner to give spark to #1, basically, follow the lines under the cap)
and i think this is what you mean by by psngr and driver side is 1357 on driver side and 2468 on passenger
