it is on a 1979 305 that is actually in an elcamino but should not be any different than a truck i am assuming. this piece of crap that has been dubbed a carburetor will not work worth a crap, we rebuilt it about a week ago and we cannot get it tuned it has been running like crap and today it wont even start and backfires really bad through the tailpipes and everyonce in a while through the carb but not very much i dont know what to do but i am thinking of putting a new carb on this thing anyways as we have been talking about it for a long time but i would still like to be educated on these carbs.
