Question about 340 vs. 440 (From newbie)

To the OP: What year(s) Barracuda or Road Runner are you thinking about owning one day? Will you be seeking an original car, or something modified? Those answers will narrow down what is likely to be under the hood of what you seek. For example - 68-69 Roadrunner standard engine was the 383, with the Hemi as the only option in 68-69 (until the mid year 440-6 in 69). The same years GTX standard engine was the 440 with the Hemi as the only option. Now if you want the last year Roadrunner trim in a Volarie body, we're talking 318 as the base engine. If modified is what you are after, just find one that looks good and kicks *** on the road and enjoy it.
