i am planning on building a LS3 but will be converting to cable driven throttle. I already know that the reluctor on the crank has to be 24x and the timing gears have to be from the LS2. My question is in regards to the PCM. Which is the best to use? I know that the LS3’s is set up for 58x. Do I use a LS1 pcm or could I possibly use the LS2’s? Thank you in advance.

You’ll need a 411 or 896 ecm for dbc.
