Why would you build a v6 instead of just running a V8 swap? Weight?
Its not a weight thing truthfully. Most do it because they dont want to buy another car, or cant afford to. Very few accomplish thier goal of a built monster v6. But those few spend big bucks on cams, heads, boost etc, etc. They probably sink enough into the six that they could have bought a v8. There is a cammed, procharged v6 on youtube thats mean.Slower than a v8. Ha. Can't be enough weight to matter.
