For carbed set up you will need the intake $270 is the cheapest i found and the MSD 6LS1 box $280 is the cheapest i found.
Thats about $550 right there, and you still need a carb. I have a $550 Proform carb set up so about $1100 not including my 6.0l motor, cam, headers etc......
But sure looks good!
