One thing you'll find as you get into your old Oldsmobile is that the kind of production records you'd think would be available actually aren't. Broad numbers are, but, for example, how many like yours were made with a particular option or something like that is not available. Oldsmobile, when it existed, couldn't even tell you where the car was originally sold or what it's invoice price was, even if you gave them the VIN. That information wasn't formally kept until 1977.
Anyway, we can tell you that the base engine in your car was, as noted, a 425 V-8 putting out 310 hp. Slightly lower power (300 hp) and higher power (365 hp) versions were available.
Your car is called a Holiday Coupe, it had a base price of $3069, and production totaled 20,768, making it the second-least produced Dynamic 88 that year. Highest production was the 4-door post sedan (Celebrity Sedan) at 38,742. Production of the 4-door hardtop (Holiday Sedan) was 30,784, while that of the convertible was 5,540.
How many are left today can't be precisely determined. Vehicle scrappage rates given by the federal government suggest an average of about 1% of a vehicle's original production will still be on the road 25 years later, but this is a very average number. Given that, you might expect maybe around 200 of these to still be out there somewhere.
Your car's wheelbase is 123 inches, which was the same as all the other 88's (Jetstar and Delta) as well as the Starfire. It is 217 inches long and weighs 4079 lbs in base configuration.
