Just purchased a 68 camaro that had a new crate 350 engine with aluminum heads installed in 2001 by the local Chevrolet dealer, the engine suffix codes reads: 1M0923 1ZZ4
I can not find an information pertaining to this suffix number. Can someone give me a clue where I can find additional infomation on this engine. Thank you.

got it, thank you. i will get to work.

 

Only thing I have found is that the 1M refers to Target Master/Goodwrench Crate Motor.
I will stop by the dealership next week to see what they tell me about the origin of this engine. Thanks for the useful info.

 

Sure. Too bad you couldnt get much more info. Let us know what the outcome is.
