S116149: Your car was built in early March 1966.
The engine assembly date would work (Feb 19), but the engine serial doesn't match your car. The 111068 would be 116149 if it were the original engine for your car.
"HT" (350hp if a Corvette engine) could be a 65, 66, 67, 68, or 69 engine. You need to find the block casting numbers (7-digit number atop the bellhousing mounting collar, driver's side) and the date code (same place, but on the passenger side) to verify the year.
