The engine number I have in my 1973 911 E Targa is 6235579.

I have the Porsche 911 Red Book, but I am unable to locate that number in the book. I am trying to confirm what year and model the engine is from. I do know it is not original to the car. Any assistance would be appreciated.

Thank you

Here you go.. You seem to have the right engine :

You just might want to double check the engine type since the serial number is beyond the listed numbers on this page

The 623 designation would indicate the engine is a 1973 911E engine but as you note also the serial number is so out of the range. The engine type is 911/91 which means it is an engine from a 1973 911T, in that case the serial number is well within the range but then the 623 does not apply. The information on the engine is conflicting.

okay where did you read your engine number from ? lets just get back to basics .. was it from the right side of the fan shroud down on the casing ?
