I'm looking at a '69 427 4-bolt block, 512 casting. Unfortunately, it was decked by the owner while prepping it to race many years ago. I do see a faint stamped number on the oil filter housing beginning with a "7" and consisting of 6 characters total from what I can see. I have a question..
1- Are these 6 numbers consistent with what I should be seeing in a factory stamp in this location? I appreciate any help, I am trying to purchase this block and want to make an informed and fair offer. He was the original owner of this and many other corvettes. As of 1998, the car still existed, this is when he sold it.
Thanks, Dave.
ok, it is a 4 bolt 427 block. it is essentially the same as a 77 pick up truck 454 block, except for the 4 bolt mains. but you can be more confident the truck motor never went through the traps at 8500 rpm. the block stamping is gone. unless the date code is correct for your car and you are planning on re-stamping it for "numbers-matching" it is worth no more than any 454 block. my pick is a gen 6 96-02 block. easy to find. cheap. not raced. roller lifters. only downside is no mech fuel pump. even the forged rotating assy is not worth a lot as it has probably been stressed like few other cranks and rods ever have.

Yup. Thanks for that. Any info on what I can expect to see on the oil filter housing would be great. I'll attach a pic of what I'm seeing.. This was taken without cleaning the area.

i would take some white paint and force it into all the grooves and numbers. In the pics I can see quite a few. Then use a piece of wood and use it as a flat blcok and wipe off the paint on the flat surface. THe numbers should retain the paint and you will be able to read the numbers. You can also use a weak acid to bring up old stamped numbers. if the surface is completely flat but I think the paint will work for you. Phosphouric acid eats up rust, you could use a q tip with a little on it to clean some of that ruse off as well or maybe some navel jelly.
Today I went back for a better pic of the numbers on the filter housing.
I was soooo hoping to just get a good pic, decipher the vin and move on...well, that was the plan anyway.
As it turns out, it's not a corvette block at all, numbers-wise..
This is why I am so "into" the numbers.
You just never know, until you look.
Now I'm in the market for a professional with a history of bringing the deck numbers back up with the acid method. Any recommendations would be greatly appreciated.
This is without a doubt, a block from a '69 427 COPO camaro!!

No.....those cars were restored around the vin tag. Thats how ALL the restorations are. It just depends on how much you have to restore. If you have a piece of the windshield attached to the vin. Its just a 99. 9 percent restore.
