Pick An Intake
Both will work, I would go with the 1970 340 intake, I have an almost identical set up (except I have hipo 340 exhaust manifolds) in a 1970 Dart with a 318 engine and it works great. What carb do you have? I run a carter 625. You could use the 360 intake too, would work great with a thermoquad! I would buy both intakes, those are great prices!! Keith.
