I have an engine that I need help identifying. The block cast number is 3932386 and it is a 2 bolt main. The date code is L128. The VIN code is VI217HV. The intake casting number is 3927184. The crank cast number crosses to a 350. The heads are 442 series. I was told it was a 327 out of a 68 Vette. Can someone help me?
