However, we can say with confidence that it's not common. Several factors contribute to its relative rarity:
* Popularity of the 383: While the 383 was a popular engine in its time, the smaller, more fuel-efficient engines became increasingly popular as the decade progressed. This means fewer 383s were installed compared to smaller displacement options.
* Gran Coupe Body Style: The Gran Coupe was a two-door hardtop version of the Fury. While popular in general, it may have made up a smaller percentage of overall Fury production compared to other body styles (like the 4-door sedan).
* Survivor Rate: Many cars from 1970 are no longer around due to age, accidents, and neglect. This further reduces the number of surviving examples of any specific configuration.
In short, finding a 1970 Plymouth Fury Gran Coupe with a 383 is likely to be a significantly rarer find than a more common Fury model with a different engine or body style. You'd be looking at a collectible car, and its value would depend heavily on its condition and originality. To get a better idea of rarity, you could consult with Plymouth car clubs or classic car valuation resources.
