HELP!! on 5.7 in a 1969 Valiant

Is it a truck or car motor if a car motor you may have to notch k member a bit. If motor is complete just get wiring harness from Hotwire and trans kickdown cable from Pace performance call Pace perforformance they are a vendor on the site he will set you up with what you need. If it's a car motor make sure it doesn't have MDS you will have to get a delete kit for it.
