273-2 performance (or lack there of) question

Thanks to both of you - I was starting to panic a little thinking I blew it buying this car without diving in deeper while I was there. When I wanted the car, I could convince myself it was something simple - and then when I bought it, I started thinking, "what if it is something serious..." Damn mind games.......

Side note, in the folder full of receipts they gave me, I found the invoice when they bought the car in 1977 for $650!! They had it 36 years - you don't see that too much anymore.
My mom bought a 66 Chevelle in 1977 for like $750. I think that was pretty cheap for back then. I remember V-8 cars going for cheap because of the second gas crunch in the late 70's. Nobody wanted them, you could buy a 68 Charger for dirt cheap back then. Ever see what they are going for now? Anyhow, that 273 oughtta lay rubber for a city block or two even with a 2 bbl carb.
