Vintage drag race question

I actually saw one of the D/Stock Darts back in the day. My brother hauled my butt down to a Chryser dealer in Akron, Ohio to show it to me. He wanted to buy it but dad would not sign the papers! Good thing too. It was like a body in white. No options. It had the 4-speed, duel quads and camshaft change already done. The headers were in the trunk. It was kool!
If I remember this combo was said to make 275hp.
