First test fit 5.7 truck engine
I ran into the same problem you in right now but with my 69 roadrunner
I wound up converting my 2016 truck 5.7 to a car intake. I based my replacement parts off a 2016 Chrysler 300. What I had to get was intake, timing cover, water pump, heater core tubes, belt, vibration damper, alternator and a/c compressor. Parts I was able to use from the truck motor were throttle body, belt tensioner, fuel injectors, fuel rail. Hope this helps you a little.
