how many of ya'll are running rochester q-jets. most everybody around here talks em' down. i had a friend who used to rebuild em' down south, re-do two of mine and he did a fine job and i have had no problems. i have two questions. 1st my 4-barrel carb # is 7045228tk-0295. can someone decode this for me. i have info on the process of decoding it, but do not completely understand it. i need year of carb primarily. next question is , i seen a post awhile back about cutting a q-jet and modifing it for better power and mpg. i do not want to do this work myself, so does any one have a clue as to the expense of a machine shop. and obvoiusley you need a complete rebuild kit again if you have to tear it down that far to do the job ? or can one get the gaskets some other way ? thanks ahead of time for any responses. darren olander 1979 chevy cheyenne blazer 350/350 gettin down on all fours, 4 a'little x 4 play !
