I'm no pro but I did learn from 2 of the best..
the first guy did all of the Mopar pro stock stuff
back in the 70s.. he did all the heads for the Woodward garage
guys which was the hot rod shop for Chrysler.. the other guy
that I learned from... he taught.. this guy and me hired the
same day at Chrysler and became good friends and I asked a
ton of questions just to see if things had changed... he was
the one who designed the swirl chamber.... I still like playing
with it but I'll never do it for a living
