Re: 1969 Z-28 Camaro - Please Help
  See the difference of the lines that run lenghtwise down the block... on the deck? On the 0329 engine they are not straight nor are they very uniform... The broach marks are very straight by virtue of the process...

Re: 1969 Z-28 Camaro - Please Help
Thank you Gentlemen, this car is a frame off restoration cross ram, after market cross ram but absolute beautiful restoration. Also four wheel disk brakes I don't believe to be original. Orange rs white interior, white stripes, with supposedly matching numbers but no documentation. What kind of value would you put on the car today?

Re: 1969 Z-28 Camaro - Please Help
Too many variables to put a value on it...
No cowl tag photos... Is it a real Z? What leve l restoration? There are so many different Frame Off levels... what you consider to be Frame Off might not be what others consider to ba a frame off... There are some obvious problems with broach marks and etc... If you want to get it verified I would suggest contacting Jerry MacNeish and having the car checked over by him. http://www.z28camaro.com/

Re: 1969 Z-28 Camaro - Please Help
The broach marks errrr the 36 grit sandpaper marks on the block deck are the giveaway here as to being restamped... People typically dont grind blocks like this... what happens is when a block is milled square at a machine shop they use a cuttting head that leaves radial marks on the block... originally they were broached... there is a thread on this site that shows how large a block broach is... (about the size of a locomotive is how someone described it).
They then cover up the radial marks with either a file or sanding then restamp the numbers they want... If you pulled a head it would in all likelyhood have radial machining marks on the decks where it doesn't show...

[/ QUOTE ] Take a close look at James pic of a legit stamp and compare to yours. Notice the "9" and the "0"? Fonts are completely different. Also with respect to the broach marks on your block, not only are they too deep but they are not parallel. Some lines go to the left, some to the right, some straight. As Charley mentioned, a belt sander special....
