73 nova timing

[tupac]

Did you buy your stock cam new or is it the same one that was already in it? if its a old cam with alot of miles on it then you might have a worn lobe on it. with all of the things that you'll put on your car you should at leats put a bigger cam on it.

i have a 73 nova also & i put in the performer intake carb & cam.. and the stock distributor and its running fine... the only thing thats was wrong was when i had it open headers it ran like sh*t but ones i put the flows the fixed right up...now i think in need to change to HEI cuz when its at bout 4000 rpm it starts misfireing then i shift & it does it when its at 4000 again..... other than that it turned on like it use to & is runing fine,,,

Hey mxpx182lit. Listen this stock cam that you have in your car, when was it installed? The reason i ask is i had the same problem that your having, i had a 306 cam put in my 75 nova, after everything was put back together it was popping back though the carb sounding like a firecracker then it would die,there were two things wrong with it. first-the valves and the cam were not in time together,heres how to fix that. take off the drivers side valve cover,bump over the motor do not start it) until both rockerarms are down towards the intake, pull your #1 plug out get a small wire are something put it in where your sparkplug goes and feel for the piston it should be up, if not do it again until you can feel it. then drop in your distributor firing on #1 that problem is fixed. now second-make sure that you are not over tighten the rocker arms & valves. start the car loosen the rockerarms on one side (do one at a time) until they make noise then slowly tighten them until the noise stops. do all of them that way and your nova will come back alive in time for your race.
