Are you buying it from you brother or something? Why would someone sell you a $1500 engine and a $500 transmission for $280. Is it a LS1 out of the Camaro or Firebird? The cheapest way to do the swap is by buying a donor Car. Just about everything is different from the V6 to the V8 all the way to the gages. Every bracket, brace hose vacuum line, The best way to describe it is the cars goes together like a very precision and complicated puzzle. Ever try to combine two puzzles and come up with a new picture?
