Engine Swap plans

I am trying to solve a few questions and guess I am not searching the correct terms.

My wife and I are currently saving to buy a house, but we have planned that as soon as we get a garage work will start on her 1955 Chevy 210 and also more in depth work on the Avy.

The current plan is to either supercharge the 5.3 or get a crate 6.0.? If we go the route of the 6.0 then the 5.3 would get rebuilt and dropped into her '01 V6 Silverado 2wd 1500, which becomes a toy project once she has a different daily driver (regular cab truck and she wants a trailblazer SS or some SUV with four doors once we have kids, She says she won't take the Avy from me).? ?But after the searching i have done on here it seems that a supercharger would be the best overall way to go the a 6.0,    >:D could always get a 6.0 for her truck, it has the fiberglass bed so it is nice and light.

My main concern is would the computer from the Avy have to migrate with the 5.3 and how would that affect my Predator?? The model I have will work on a 6.0 4.8 and 5.3, but won't the VIN for the Avy be for a 5.3 and? her truck be the 4.8?? Or would the computers in each truck learn their new engines or would they still think they had the smaller engines until I had them programed.  I would most likely get a supercharger kit with a custom tune for the Avy, but if the Silverado gets a different engine I would like to move the predatorto her truck.
 
You are getting into more issues than you think with the motor swap... The 5.3L tune will also include the tranny parameters since GM did away with a seperate controller for the 4L60E. I say this because if you go with a 6.0L, it will require you to answer the 4l65E or 4L80E question to run behind the 6.0L. The 4L80E tune is a different animal...

as far as the Vin #'s are concerned, that will not be an issue with real tuning software since you can rewrite the entire PCM. Not sure if the handheld will allow that option. If you go with the supercharger option you will be tossing the predator anyway since it will be little use to you for the tuning/logging involved with the blown application...

Either way, you will have to retune both trucks anyway after the swap....

Good Luck... (y)
 
I didn't know that the tranny parameters weren't a seperate module, seems like the best way to go then would be to supercharge the Avy.

I figured though that if I put a 6.0 in the Silverado though I would be able to get the predator unmated from the avy and then use it on the silverado.  Of course since I would have to have that pcm reprogramed from a V6 to a 6.0 would prolly be easier to havea tune done then.

You are starting to see one of the many reasons why the predator might not be the best choice when doing this type of thing. It is fine for minor tweaks to NA motors, but when doing any heavy lifting the HPT/EFI Live option will never leave you stranded...

Good Luck.. and keep us informed on your progress... we might help keep you on the straight and narrow... (y)
