I'm sure that Technology has Improved......but back in the Sixties......I know that the Police had a method of lightly heating the Stamp Pad with a torch, then they would apply some sort of Acid to the Pad and it would bring up any Stampings that were pre-existing....
I know of a couple guys that were "Busted" by this procedure ........

Its possible that a non original motor car started out as a factory blank pad and not a reground one. Therefore an acid test doesnt prove anything with 100% certainty really.

Interesting points. I did not know there was a test that could be repeated. Also, the blank pad point is also a good one. Maybe if we all ask nicely the restamping will stop.

very good point. i guess it could only "dis-prove" originality...in other words...if there was a prior stamping, it would show..if it was never stamped, it would show nothing. I guess it would prove if it was the "original stamping" or not...the question being ... when was it stamped?? Does anyone have pics of another similar dated motor?? Do the cast and assembly date seem in order?? What about the alpha-numerics...sure'd like to see photos of other stampings for comparison...

did you get the head off yet and check the broach marks????? great site guys...learning every day!!

Tomorrow is the last day of the crusin the coast show, I'll be heading home then. I bought a gasket set!

There are estimated to be over 6,000 classic cars this year, one of the best showings ever. Many 69's and a lot of hemi cuda's and clones. The car corral and swap meet was pretty dismal this year. Everyone's parts were ruined by the hurricane. Some of you northerners should come down next year, you'd make a killing!

Two respected people in the hobby have looked at pictures of the stamp (and I need to stress that it was just pics, they or one of them need to see it in person) and at first glance, the stamp seems to be in line with other MP stamps from that time frame. Cast and assembly dates line up, not sure if the chevelle VIN and assembly dates line up, anyone know dates ranges on chevelle vins?

The head will come off early next week, and I should know more.

Real question is that everyone seems to agree that it is a L72 engine, if so, what could it have been out of if not the chevelle whose vin is stamped by the oil filter? I have learned to start by attempting to find the (or not so) obvious and disprove first, then work on proving.

As I replied earlier & going on just what your brief pictures show,that VIN # shows up as a Chevelle or Elcamino,assembled July 1969 from the Kansas City Leeds plant.

[/ QUOTE ] It could be many things if it was restamped. CE warranty motor, boat motor,truck motor,and if you take it further it could have been a converted 2 bolt from an impala,just to name a few of the possibilities.
