Today, dollar for dollar, is the 318 faster than the 340 ???

I almost bought a 65 Marlin. Look wise it was kind of cross between a 66 Barracuda and 66 Charger.
I was looking at what I thought was Charger for over 5 years. It was sitting beside a barn a fair distance from the road.
Turned out to be a Marlin. Cool car.
