Bill, I was just referring to the 440 cid engines. I know others (Max Wedge, for instance) were previously stamped HP. If I recollect the first 440 to have the HP stamp was the 375 HP/TNT in 1967. Of course, my recollection is getting fuzzy these days. Also, if I recall, the 1967 TNT was the first TNT to have internal changes (valves & cam) to account for the extra horsepower, whereas the 1966 was mostly rated on a tweaked carburetor and dual exhausts. Like I say, my recollection............ Jack On Jan 18, 2006, at 10:07 PM, William Miller wrote: > Jack > I had a 63 383 Plymouth Savoy police car I bought new.
