I don’t know how good the Chevy inventory control system was in 1969 but Yes I do think the engine production number can go much higher than the car production on SHP engines. They have a history of doing that.
The SHP 427 Corvette engine production went much higher than car production numbers (from Corvette web sites so not sure if they are 100% but was same on different sites )
1967: 277 L88 engines , 20 L88 Corvettes built
1968: 615 L88 engines , 80 L88 Corvettes built
1969: 213 L88 engines , 116 L88 Corvettes built
1969 94 ZL1 engines , about 3 ZL1 Corvettes built.
They even built SHP engines for cars that were never built
14 Engines built for the 1971 LS6 Chevelle , no production cars built
Some engines have been found with COPO suffix codes and no vin number stamped on the block.
Tonawanda built a lot of engines and stamped many different suffix codes
12 engine suffix codes just for 1969 396 Camaro/Chevelle
18 engine suffix codes just for 1969 427 Passenger
suffix codes just for a Heavy Duty Clutch or a Police package
