Depends on alot of factors. There aren't that many 67-68 fastbacks out there. I would base my purchase on the overall condition of the car, not just the engine it's equipped with. The 390 is more rare, and most likely more valuable in a collector sense. The 289-302 is arguably more streetable if you plan on driving it. The biggest difference is that one is a small block (smaller displacement, and lighter) the other is a big block (bigger and heavier). The 390 is capable of producing alot of torque. Really the 289-302 is as well, but they say that big blocks can make it more easily.

i don't know the difference in weight, but the 390 would make up for it in torque. If you want a high revving car, stick to the 302 because of its stroke is shorter than the 390, but the 390 is a beast, Im more of a 390 fan...hope this helps
