got an engine want to know what its from

[Ericster]

i got a 240z but it doesnt have the original engine in it. I want to find out what car the engine came from anybody know were i can plz help

[MikeW]

Can you post a picture of the engine?

[Carl Beck]

Better still - Post the engine serial number. It's on the side of the block, just below the #5/6 spark plugs... There are two pads cast in the block - and the engine serial number will be stamped into them...

[MikeW]

Carl, I started to suggest that as well but with the little information provided for all we know it could be a V8.

its a stright 6 the engine number is L24 053418

[MikeW]

How do you know it's not original? An L24 is the stock engine. What is the build date (driver door jamb tag)? Your engine was likely produced for a car built in August or September of 1971.

The car this engine came from likely had a manufacture date of 8/71 or 9/71. There is no way to tell for sure. What is the build date of your car?

[Ericster]

its a 71' ill have to look for the month. the previose owner said that it was a different engine. ill post later for the month

the vin plate on the pass side fender will tell you the serial no of the engine your car came with....

Not meaning to hijack thread but, I have the same situation. 76 280z, build plate says engine should be 084449 but has engine L28-216277. I was wondering is there an engine database to search through for the year of engine? Also has N-42 head. Could I have original head with later short block? Thanks for any info.

That's a shade under 60000 before mine. But you VIN is just under 163000 prior to mine. My engine is 275875 and it's the original engine and N47 head, build date 5/78. 78 didn't have the engine number on the VIN plate. Doesn't really answer your question but it might help establish a point of reference.

Thanks Stephen. So I can reasonably say that I'm still dealing with a 280z engine and not a zx mill. Thanks again.
