Thank you for your answers! The engine number is: K102808J-4CH156468 The "J" in the number stands for Chevrolet Motor Division as it is listed in my Owners manual! The distributor is in the rear of the engine! Yes we have 98 octane petrol in our country, but I will fill in 91 octane now! Can you say me wher my 1982 Regal was built? Thank you!
