Ok, I have a 1970 trans am that I picked up out of a field a while back and Im going through the numbers now and wanted to know what this engine is I have! First off the block casting number on the passenger side is 9799914 the stamp on the front is a YS with the number above that being C007817, I havent taken the valve covers off yet to get a number in there, but the heads are 48 and it looks as if it has a D017 cast into them also! the casting number near the water pump on the front of the block are very faint and I am not good enough to see what is in there, but it looks like a 699?111? I am very sure about the 699 and some ones that could be 7's also, I also have a carb on the car, but its newer I think, but the numbers on it are 17086045 also 2775 JPH. Im not really a pontiac guy when it comes to numbers I have a 100% original 70 *** but decoding this motor and car for that matter has been a headach, so any help would be great, thanks
The car also has a turbo 400 automatic
