GM 3400 Model & Year Differences

[myowneq]

Hello again.

Another question, another topic.

I want to start building up a 3400 from the ground and am looking ofr a 3400 for cheap but I need some information.

Is the GM 3400 motor the same among all the different cars in the same year regardless of car or suv? I found a 3400 motor with no accessories or wiring harness from a 99 Venture. Kind of curious if it is a direct replacement for my 02 3400 if it is rebuilt.

Any help is greatly appreciated.

Thanks,
Timothy
