We have an 83 Delta 88 Royale. The in it is not an 83 Delta . We do know that it is a 307 with 7A heads. That gives us the years 85-90. , we need to replace the MAP sensor, but we can not the to get the part! The parts store is no help at all. I do not that it is a Delta at all. Possibly Toronado or Custom . Does anyone know how to find out what year and what it might have come out of? Thanks all!

    take the map sensor out of the car and take it to the parts store and they should be able to match it up.

    We have an 83 Olds Delta 88 Royale. The engine in it is not an 83 Delta engine. We do know that it is a 307 with 7A heads. That gives us between the years 85-90. Anyway, we need to replace the MAP sensor, but we can not identify the engine to get the part! The parts store is no help at all. I do not believe that it is a Delta engine at all. Possibly Toronado or Custom Cruiser. Does anyone know how to find out what year and what it might have come out of? Thanks all!

    Well to find out you can go under the car and look on top of the oil pan, it should say right there. You might have to work a little to get your eye balleeez up there.

    Look for a stamping on the block and take the numbers to a dealer.
