Don't overlook the humble early/mid 60s Nova. A very pedestrian looking ride, but a lot of space under the hood. And a 350 V8 from a wrecked vette is very nearly a drop in / bolt up engine swap. Just needs a different oil pan, water pump, and for lots of stop and go driving, a bigger radiator. A '63 Nova with the 350 in it will run like a turkentine cat, and nobody looking at you sitting at the light would ever suspect that you can absolutely smoke many of the so-called muscle cars until you pop clutch and stomp gas. If you get a real expert to match the engine, rear end, tranny, carb(s) and headers, that granny car will impress and delight you but not break you at the gas pump. I had a '63 and most of the identifying chrome was gone, making it almost a mystery car. . . .
That's why the Beach Boys wrote the song about it:
"She's my little deuce coup, you don't know what I got."
