452 nailhead?

Guy here is advertising a really nice looking 64 Buick Wildcat two-door hardtop Sport Coupe for a fair price..He sez it has a 7.3 liter 452 cubic inch engine innit..never heard of of one..like the 401 or 425 is he reading the ft. lbs. of torque number on the air cleaner decal?

 

yeah
he made a typo
its 425 not 452

 

No, just a typo, or he's dyslexic. 452=425 (Or, he's an idiot - there's always that possibility!)
