Thursday Twister: Name That Car

It is time for a brain teaser for all the car geeks in the audience.  Typically the Thursday Twister is a game where we name all the cars with such-n-such a feature, but today I’m going to make it a simple quiz with a single answer.  What single make/model automobile, over the span of two model years, was available from the factory with a pushrod inline-4, an overhead cam inline-6, and a V8?

Actually, depending on how you classify model, there might be two make/models that meet this puzzler…maybe more, but you guys will have to figure it out!
