just bought a bare 5.7 block and 853 heads from a customer of mine for $250 bucks!! gonna start my build. I have a 4.8, so this will be a big change. gonna take my time with it. gonna keep it somewhat mild, well try. anything i need to keep in mind for this swap? will the wiring be the same? i will use my intake off the 4.8. im sure i will need bigger injectors, dunno about the computer though?

 

will my acc. still bolt up? thanks for the help

 

In short, Yes! Just swap all the truck stuff over. The blocks are basically the same demensionally.
