327 block numbers 3782870 front of block FobI9HO ( the little b may be a 6 ). Heads are 194 double humb 8782461. I don't remember my early 327 stuff but it has a small harmonic balancer and the vent can in the valley. I think it is a 300HP Impala or Vette?. Are these worth anything to restorer or OK to use in a cheap Hot Rod?.......Thanks Jim
