Re: 1968 427 Chevelle engine stampings

For 1968, I found this... 1968


Block casting shows 3935439....427.......68-69...2 or 4 bolt

The J in the poartial VIN would indicate the Jnesville assy plant, which made full size cars, it is from an Impala, Bel Air, Biscayne or Caprice. I am not aware of any proven 427 in a Chevelle, and the J would rule it out anyway, as Chevelles were never made there.
That engine is a goldmine to the right person...

It is a rare man who can count his own blessings and not mistake them for personal achievements.
