i just put in a rebuilt 327 out of a 67 corvet that has the 289 short crank the one with out the harmonic balancer inset screw. and i get the damned theing to start for a few seconds and then it shoots flames out the carb. i' reset and reset and reset the timing but it does the same thing so i took all the pullies of and set the timing manualy it still does it. could it be a faulty carb or maybe the fuel pump or perhaps im not getting enoph suction or something anyone got any clues please help aprils right around the corner and thats when my local racing strip opens
