or can you tell me about your 4.5 conversion and what i need.

From my knowledge the blocks are the same. I know the efi system onto the tb42 is popular. So one would assume it's either piston/ bores are different or its all in the head???
The 4.8 is a completely different engine so yea no point with that.
