Well lets see here 2002 to 2009 Trailblazers with straight sixes.This happens to be 2011.Where are they now.And as for forked 8s Old Henry saw the light in 1931 and started building V/8s for the 1932 Fords.True there were several Ford straight sixes,but they have also disappeared.They are evidently not what the buying public wants.So now we are left with the V/6es and V/8s Which perform so much better than the old straight sixes.I can remember whe the Sportsman class at the local dirt track,was all straight 6 engined cars.But after a while they opened it up to 310 cu.in V/8s and guess what. The V/8s ran away with everything.
