74 truck 360 for a 70 dart

i also have a 360 from a 74 pick up and you will have to change the oil pan.. you also need a V8 k frame unless you already havea V8. its differet from a slant k frame..

as for 200.. i got my motor and 727 tranny for 300

theres other things like ignition and exhaust things that you will run into.
