well i have this 350 in my 72 C10, we have been trying to get this thing started but we can't so here are the symptoms and see if yall can help me get this started.

well at first the we wernt getting gas to the fuel pump but now we are, at first we wernt getting spark but now we get alittle every once and a while, it backfired out the exhaust once but only once but it keeps backfiring out the carb, no we figure its the timming but all the measurement tell us we are in the ball park to start it, the distributer is good and all the wires go to the right places and the spark plugs are new, looking at the front of the engine the timming marks are on the right side of the balancer but my dad thinks that it might have supposed to have been on the left side (he says some engines were like that, but i don't see any holes for the mark and the water pump makes it so you can't see nothin.



PLEASE HELP!!!!!!!!!!!!!!!!!!!!
