I'm on the verge of swapping in a real motor into my 99 vette but I don't wanna go in over my head.

I've read motor mounts and transmission bolt up already but what I'm afraid of is the wiring? If it's manageable I'd like the 6.2 and have a buddy waiting for my stock ls1 to put in a Mustang. So anybody who has ever done a swap like this that could put in their 2 cents about all the problems they encountered it would be appreciated

It's the same as any swap going from a Gen III to Gen IV really. Getting it to run will be easy. Making sure every thing communicates with the vette electronics will be the hard part. You might want to consider using the LS1 PCM and harness you have and use a Lingenfelter converter box for the cam and crank signals.

I'm not too sure what would be necessary to run the LS3 harness and PCM in a C5 unfortunately.
