Thanks for the info guys! I was actually planning on using a TH-400 or 700r4 with an adapter plate from Advanced Adapters and keeping the mechanical speedo operational. And I was just planning on using a high pressure (EFI) inline fuel pump on the stock tank or a blazer rear tank, would that not work? Motor mounts probably wouldnt be a problem I think I can fab up a plate or something. I assumed I could use the same drive shaft and everything, why would I need something else if I am using the same tranny?
What does it cost to have the PCM programmed to remove the not needed mentioned stuff? As far as the VATS, what is the BCM?
I don't think the accessories are any different on the 5.3 than the 5.7 because alot of the Camaro/TransAm guys swap to the 5.3 heads to get higher compression. Maybe the assesory brackets are different but definatly not the thread holes. I'm pretty sure they is plenty of room under the hood for everything!
Again, thanks for all the help...
