I inherited my Dad's 74 Charger 318. It is a Wisconsin car that he drove till 1986. So not to pretty, interior is nice an ok driver. He always had plans of fixing it up but is health didn't allow that. I put mags with 50s on it dual glasspack exhaust and have been driving a little for the last couple years. I have a 440 (my old bracket motor) that I want to put in. Looking for advice on motor mount , 1-7/8 or 1-3/4 headers would like to keep P/S. Shifter linkage. Will column shift from 904 to 727 be same? Any other advice.
