A friend runs local short dirt oval,408" good comp,W2 heads and magunum manifolds! He does it just because he wins and the other racers(chevy guys) can't figure out how a lowly overweight mopar(300lbs or more heavier) can run that fast,he has to sandbag to keep most on the same lap. I'm building him another 408 but Im trying to get him to put headers on this one.Lol
