my chevy rods are H beams & chev didn't make H beams so i'm off the hook on that one just like my Ford 9" is made by Strange & Romac, saved again. The chevy valves in my -1 heads are made by Manley so altho there are no Mopar parts on my Maxx block engine, there are no chev or ford parts either, same with my 727 sooooooooo.... my True no Ford or Chev racecar runs 9.4, so is that fast enuff for you?
